## What is a Cube Root (Page 4/7)

(Contiued from page 3 )

Question - Type 4 -

Find the cube root of 0.008

Answer - 4-

Multiple the number with 1000 or 1000000 or 1000000000,

then find the cube root.

The result to be divided with 10 or 100 or 1000 as the case may be.

In this case multiple it with 1000 i.e. .008 * 1000 = 8;

now the cube root of 8 is 2.

Divide it with 10 and the result is 2/10=0.2

Question - Type 5 -

Find the cube root of 343/125

Answer - 5-

First find the cube roots separately i.e.

343=7*7*7 therefore cube root is 7

125=5*5*5 therefore cube root if 5

The cube root of 343/125 will be 7/5
