Answer:_______________ |
| 1) What is the positive square root of 5929 Answer: 77 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 5929. Figure out which number squared (multiplied by itself) equals 5929. The number 772 squared equals 5929. 5929 = 77 × 77 = 5929 So the positive √ 5929 is 77. |
| 2) What is √ 676 Answer: 26 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 676. Figure out which number squared (multiplied by itself) equals 676. The number 262 squared equals 676. 676 = 26 × 26 = 676 So √ 676 is 26. |
| 3) What is √ 25 Answer: -5 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 25. Figure out which number squared (multiplied by itself) equals 25. The number -52 squared equals 25. 25 = -5 × -5 = 25 Finally, include the negative sign to get the negative square root. So √ 25 is -5. |
| 4) What is the positive square root of 7225 Answer: 85 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 7225. Figure out which number squared (multiplied by itself) equals 7225. The number 852 squared equals 7225. 7225 = 85 × 85 = 7225 So the positive √ 7225 is 85. |
| 5) What is √ 576 Answer: 24 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 576. Figure out which number squared (multiplied by itself) equals 576. The number 242 squared equals 576. 576 = 24 × 24 = 576 So √ 576 is 24. |
| 6) 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 Finally, include the negative sign to get the negative square root. So √ 9 is -3. |
| 7) What is the positive square root of 3844 Answer: 62 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 3844. Figure out which number squared (multiplied by itself) equals 3844. The number 622 squared equals 3844. 3844 = 62 × 62 = 3844 So the positive √ 3844 is 62. |
| 8) 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 So √ 225 is 15. |
| 9) 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 Finally, include the negative sign to get the negative square root. So √ 361 is -19. |
| 10) What is the positive square root of 9409 Answer: 97 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 9409. Figure out which number squared (multiplied by itself) equals 9409. The number 972 squared equals 9409. 9409 = 97 × 97 = 9409 So the positive √ 9409 is 97. |
