Answer:_______________ |
| 1) What is 3√ 64 Answer: 4 SOLUTION 1 : Remember:
Taking the cube root ( 3√ is the inverse of cubing. for example, 3√ 125 = 5 since 125 = 53
A perfect cube is the result when an integer is multiplied by itself, and then multiplied by itself again. For example, 125 is a perfect cube because 5 × 5 × 5 = 125. The cube root of a perfect cube is always an integer. Solve; You want to find so figure out which number cubed ( multiplied by itself,and the nmultiplied by it self again) equa ls 4. The number 4 cubed equals 64. 43 = 4 x 4 x 4 = 64 So , 3√ 64 is 64 |
| 2) What is the cube root of 2744 Answer: 14 SOLUTION 1 : Remember: Taking the cube root ( 3√ is the inverse of cubing. for example, 3√ 125 = 5 since 125 = 53
A perfect cube is the result when an integer is multiplied by itself, and then multiplied by itself again. For example, 8 is a perfect cube because 2 × 2 × 2 = 8. The cube root of a perfect cube is always an integer. Solve: You want to find the cube root of 2744, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 2744. The number 14 cubed equals 2744. 143 = 14 × 14 × 14 = 2744. So the cube root of 2744 is 14. |
| 3) What is 3√ 125 Answer: 5 SOLUTION 1 : Remember:
Taking the cube root ( 3√ is the inverse of cubing. for example, 3√ 125 = 5 since 125 = 53
A perfect cube is the result when an integer is multiplied by itself, and then multiplied by itself again. For example, 125 is a perfect cube because 5 × 5 × 5 = 125. The cube root of a perfect cube is always an integer. Solve; You want to find so figure out which number cubed ( multiplied by itself,and the nmultiplied by it self again) equa ls 5. The number 5 cubed equals 125. 53 = 5 x 5 x 5 = 125 So , 3√ 125 is 125 |
| 4) What is the cube root of 1331 Answer: 11 SOLUTION 1 : Remember: Taking the cube root ( 3√ is the inverse of cubing. for example, 3√ 125 = 5 since 125 = 53
A perfect cube is the result when an integer is multiplied by itself, and then multiplied by itself again. For example, 8 is a perfect cube because 2 × 2 × 2 = 8. The cube root of a perfect cube is always an integer. Solve: You want to find the cube root of 1331, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 1331. The number 11 cubed equals 1331. 113 = 11 × 11 × 11 = 1331. So the cube root of 1331 is 11. |
| 5) What is 3√ 8 Answer: 2 SOLUTION 1 : Remember:
Taking the cube root ( 3√ is the inverse of cubing. for example, 3√ 125 = 5 since 125 = 53
A perfect cube is the result when an integer is multiplied by itself, and then multiplied by itself again. For example, 125 is a perfect cube because 5 × 5 × 5 = 125. The cube root of a perfect cube is always an integer. Solve; You want to find so figure out which number cubed ( multiplied by itself,and the nmultiplied by it self again) equa ls 2. The number 2 cubed equals 8. 23 = 2 x 2 x 2 = 8 So , 3√ 8 is 8 |
| 6) What is the cube root of 512 Answer: 8 SOLUTION 1 : Remember: Taking the cube root ( 3√ is the inverse of cubing. for example, 3√ 125 = 5 since 125 = 53
A perfect cube is the result when an integer is multiplied by itself, and then multiplied by itself again. For example, 8 is a perfect cube because 2 × 2 × 2 = 8. The cube root of a perfect cube is always an integer. Solve: You want to find the cube root of 512, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 512. The number 8 cubed equals 512. 83 = 8 × 8 × 8 = 512. So the cube root of 512 is 8. |
| 7) What is 3√ 343 Answer: 7 SOLUTION 1 : Remember:

A perfect cube is the result when an integer is multiplied by itself, and then multiplied by itself again. For example, 125 is a perfect cube because 5 × 5 × 5 = 125. The cube root of a perfect cube is always an integer. Solve; You want to find so figure out which number cubed ( multiplied by itself,and the nmultiplied by it self again) equa ls 7. The number 7 cubed equals 343. 73 = 7 x 7 x 7 = 343 So , 3√ 343 is 343 |
| 8) What is the cube root of 343 Answer: 7 SOLUTION 1 : Remember: Taking the cube root ( 3√ is the inverse of cubing. for example, 3√ 125 = 5 since 125 = 53
A perfect cube is the result when an integer is multiplied by itself, and then multiplied by itself again. For example, 8 is a perfect cube because 2 × 2 × 2 = 8. The cube root of a perfect cube is always an integer. Solve: You want to find the cube root of 343, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 343. The number 7 cubed equals 343. 73 = 7 × 7 × 7 = 343. So the cube root of 343 is 7. |
| 9) What is 3√ 512 Answer: 8 SOLUTION 1 : Remember:
