Answer:_______________ |
| 1) What is √ 81 Answer: -9 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 81. Figure out which number squared (multiplied by itself) equals 81. The number -92 squared equals 81. 81 = -9 × -9 = 81 Finally, include the negative sign to get the negative square root. So √ 81 is -9. |
| 2) What is the positive square root of 3249 Answer: 57 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 *3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 3249. Figure out which number squared (multiplied by itself) equals 3249. The number 572 squared equals 3249. 3249 = 57 × 57 = 3249 So the positive √ 3249 is 57. |
| 3) What is √ 169 Answer: 13 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 169. Figure out which number squared (multiplied by itself) equals 169. The number 132 squared equals 169. 169 = 13 × 13 = 169 So √ 169 is 13. |
| 4) What is √ 289 Answer: -17 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 289. Figure out which number squared (multiplied by itself) equals 289. The number -172 squared equals 289. 289 = -17 × -17 = 289 Finally, include the negative sign to get the negative square root. So √ 289 is -17. |
| 5) What is the positive square root of 3364 Answer: 58 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 *3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 3364. Figure out which number squared (multiplied by itself) equals 3364. The number 582 squared equals 3364. 3364 = 58 × 58 = 3364 So the positive √ 3364 is 58. |
| 6) What is √ 361 Answer: 19 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 361. Figure out which number squared (multiplied by itself) equals 361. The number 192 squared equals 361. 361 = 19 × 19 = 361 So √ 361 is 19. |
| 7) What is √ 625 Answer: -25 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 625. Figure out which number squared (multiplied by itself) equals 625. The number -252 squared equals 625. 625 = -25 × -25 = 625 Finally, include the negative sign to get the negative square root. So √ 625 is -25. |
| 8) What is the positive square root of 4489 Answer: 67 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 *3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 4489. Figure out which number squared (multiplied by itself) equals 4489. The number 672 squared equals 4489. 4489 = 67 × 67 = 4489 So the positive √ 4489 is 67. |
| 9) What is √ 4 Answer: 2 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 4. Figure out which number squared (multiplied by itself) equals 4. The number 22 squared equals 4. 4 = 2 × 2 = 4 So √ 4 is 2. |
| 10) What is √ 729 Answer: -27 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 729. Figure out which number squared (multiplied by itself) equals 729. The number -272 squared equals 729. 729 = -27 × -27 = 729 Finally, include the negative sign to get the negative square root. So √ 729 is -27. |
