1)  

What is the cube root of 1

Answer: 1


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 1, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 1.

The number 1 cubed equals  1.

13 = 1 × 1 × 1 = 1.

So the cube root of 1 is 1.



2)  

What is 3 1 

Answer: 1


SOLUTION 1 :

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 1.
The number 1 cubed equals 1.
 

 13 1 x 1 x 1 = 1

So , 3 1  is 1



3)  

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.



4)  

What is 3 729

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 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, 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 729, so figure out which number cubed (multiplied by itself, and then multiplied by itself again) equals 729.

The number 9 cubed equals  729.

93 = 9 × 9 × 9 = 729.

So the cube root of 729 is 9.



6)  

What is 3 64 

Answer: 4


SOLUTION 1 :
