| 1) What is √ 324 Answer: 18 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 324. Figure out which number squared (multiplied by itself) equals 324. The number 182 squared equals 324. 324 = 18 × 18 = 324 So √ 324 is 18. |
| 2) 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 Finally, include the negative sign to get the negative square root. So √ 169 is -13. |
| 3) What is the positive square root of 2025 Answer: 45 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 2025. Figure out which number squared (multiplied by itself) equals 2025. The number 452 squared equals 2025. 2025 = 45 × 45 = 2025 So the positive √ 2025 is 45. |
| 4) 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 So √ 25 is 5. |
| 5) What is √ 900 Answer: -30 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 900. Figure out which number squared (multiplied by itself) equals 900. The number -302 squared equals 900. 900 = -30 × -30 = 900 Finally, include the negative sign to get the negative square root. So √ 900 is -30. |
| 6) What is the positive square root of 8649 Answer: 93 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 8649. Figure out which number squared (multiplied by itself) equals 8649. The number 932 squared equals 8649. 8649 = 93 × 93 = 8649 So the positive √ 8649 is 93. |
| 7) 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. |
| 8) 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 Finally, include the negative sign to get the negative square root. So √ 676 is -26. |
| 9) What is the positive square root of 2401 Answer: 49 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 2401. Figure out which number squared (multiplied by itself) equals 2401. The number 492 squared equals 2401. 2401 = 49 × 49 = 2401 So the positive √ 2401 is 49. |
| 10) 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. |
