Answer:_______________ |
| 1) 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. |
| 2) What is the positive square root of 1849 Answer: 43 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 1849. Figure out which number squared (multiplied by itself) equals 1849. The number 432 squared equals 1849. 1849 = 43 × 43 = 1849 So the positive √ 1849 is 43. |
| 3) 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. |
| 4) What is √ 144 Answer: -12 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 144. Figure out which number squared (multiplied by itself) equals 144. The number -122 squared equals 144. 144 = -12 × -12 = 144 Finally, include the negative sign to get the negative square root. So √ 144 is -12. |
| 5) What is the positive square root of 9801 Answer: 99 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 9801. Figure out which number squared (multiplied by itself) equals 9801. The number 992 squared equals 9801. 9801 = 99 × 99 = 9801 So the positive √ 9801 is 99. |
| 6) What is √ 400 Answer: 20 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 400. Figure out which number squared (multiplied by itself) equals 400. The number 202 squared equals 400. 400 = 20 × 20 = 400 So √ 400 is 20. |
| 7) 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. |
| 8) 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. |
| 9) 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. |
| 10) What is √ 1 Answer: -1 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 1. Figure out which number squared (multiplied by itself) equals 1. The number -12 squared equals 1. 1 = -1 × -1 = 1 Finally, include the negative sign to get the negative square root. So √ 1 is -1. |
