Answer:_______________ |
| 1) 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 So √ 729 is 27. |
| 2) What is √ 225 Answer: -15 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 225. Figure out which number squared (multiplied by itself) equals 225. The number -152 squared equals 225. 225 = -15 × -15 = 225 Finally, include the negative sign to get the negative square root. So √ 225 is -15. |
| 3) What is the positive square root of 9216 Answer: 96 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 9216. Figure out which number squared (multiplied by itself) equals 9216. The number 962 squared equals 9216. 9216 = 96 × 96 = 9216 So the positive √ 9216 is 96. |
| 4) What is √ 196 Answer: 14 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 196. Figure out which number squared (multiplied by itself) equals 196. The number 142 squared equals 196. 196 = 14 × 14 = 196 So √ 196 is 14. |
| 5) 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. |
| 6) What is the positive square root of 4761 Answer: 69 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 4761. Figure out which number squared (multiplied by itself) equals 4761. The number 692 squared equals 4761. 4761 = 69 × 69 = 4761 So the positive √ 4761 is 69. |
| 7) What is √ 484 Answer: 22 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 484. Figure out which number squared (multiplied by itself) equals 484. The number 222 squared equals 484. 484 = 22 × 22 = 484 So √ 484 is 22. |
| 8) What is √ 16 Answer: -4 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 16. Figure out which number squared (multiplied by itself) equals 16. The number -42 squared equals 16. 16 = -4 × -4 = 16 Finally, include the negative sign to get the negative square root. So √ 16 is -4. |
| 9) What is the positive square root of 6400 Answer: 80 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 6400. Figure out which number squared (multiplied by itself) equals 6400. The number 802 squared equals 6400. 6400 = 80 × 80 = 6400 So the positive √ 6400 is 80. |
| 10) What is √ 9 Answer: 3 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 9. Figure out which number squared (multiplied by itself) equals 9. The number 32 squared equals 9. 9 = 3 × 3 = 9 So √ 9 is 3. |
