| 1) What is the cube root of 3375 Answer: 15 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 3375, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 3375. The number 15 cubed equals 3375. 153 = 15 × 15 × 15 = 3375. So the cube root of 3375 is 15. |
| 2) 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 |
| 3) What is the cube root of 1000 Answer: 10 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 1000, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 1000. The number 10 cubed equals 1000. 103 = 10 × 10 × 10 = 1000. So the cube root of 1000 is 10. |
| 4) What is 3√ 729 Answer: 9 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 9. The number 9 cubed equals 729. 93 = 9 x 9 x 9 = 729 So , 3√ 729 is 729 |
| 5) What is the cube root of 0 Answer: 0 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 0, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 0. The number 0 cubed equals 0. 03 = 0 × 0 × 0 = 0. So the cube root of 0 is 0. |
| 6) 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 |
| 7) What is the cube root of 216 Answer: 6 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 216, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 216. The number 6 cubed equals 216. 63 = 6 × 6 × 6 = 216. So the cube root of 216 is 6. |
| 8) 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 |
| 9) What is the cube root of 27 Answer: 3 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 27, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 27. The number 3 cubed equals 27. 33 = 3 × 3 × 3 = 27. So the cube root of 27 is 3. |
| 10) What is 3√ 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, 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 |
