1)  

What is 3 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, 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 0.
The number 0 cubed equals 0.
 

 03 0 x 0 x 0 = 0

So , 3 0  is 0



2)  

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.



3)  

What is 3 8 

Answer: 2

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



4)  

What is the cube root of 27

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.



5)  

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



6)  

What is the cube root of 216

Answer: 6


SOLUTION 1 :

Remember:
