Answer:_______________ |
| 1) What is the positive square root of 8100 Answer: 90 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 8100. Figure out which number squared (multiplied by itself) equals 8100. The number 902 squared equals 8100. 8100 = 90 × 90 = 8100 So the positive √ 8100 is 90. |
| 2) 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. |
| 3) 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 So √ 625 is 25. |
| 4) What is the positive square root of 7396 Answer: 86 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 7396. Figure out which number squared (multiplied by itself) equals 7396. The number 862 squared equals 7396. 7396 = 86 × 86 = 7396 So the positive √ 7396 is 86. |
| 5) 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. |
| 6) What is √ 529 Answer: 23 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 529. Figure out which number squared (multiplied by itself) equals 529. The number 232 squared equals 529. 529 = 23 × 23 = 529 So √ 529 is 23. |
| 7) What is the positive square root of 2809 Answer: 53 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 2809. Figure out which number squared (multiplied by itself) equals 2809. The number 532 squared equals 2809. 2809 = 53 × 53 = 2809 So the positive √ 2809 is 53. |
| 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 √ 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. |
| 10) 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. |
