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 √ 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. |
3) What is the positive square root of 2704 Answer: 52 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 2704. Figure out which number squared (multiplied by itself) equals 2704. The number 522 squared equals 2704. 2704 = 52 × 52 = 2704 So the positive √ 2704 is 52. |
4) What is √ 64 Answer: 8 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 64. Figure out which number squared (multiplied by itself) equals 64. The number 82 squared equals 64. 64 = 8 × 8 = 64 So √ 64 is 8. |
5) What is √ 441 Answer: -21 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 441. Figure out which number squared (multiplied by itself) equals 441. The number -212 squared equals 441. 441 = -21 × -21 = 441 Finally, include the negative sign to get the negative square root. So √ 441 is -21. |
6) What is the positive square root of 2304 Answer: 48 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 2304. Figure out which number squared (multiplied by itself) equals 2304. The number 482 squared equals 2304. 2304 = 48 × 48 = 2304 So the positive √ 2304 is 48. |
7) 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 So √ 81 is 9. |
8) What is √ 36 Answer: -6 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 36. Figure out which number squared (multiplied by itself) equals 36. The number -62 squared equals 36. 36 = -6 × -6 = 36 Finally, include the negative sign to get the negative square root. So √ 36 is -6. |
9) What is the positive square root of 7744 Answer: 88 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 7744. Figure out which number squared (multiplied by itself) equals 7744. The number 882 squared equals 7744. 7744 = 88 × 88 = 7744 So the positive √ 7744 is 88. |
10) What is √ 100 Answer: 10 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 100. Figure out which number squared (multiplied by itself) equals 100. The number 102 squared equals 100. 100 = 10 × 10 = 100 So √ 100 is 10. |
