Question

Find the cube of (0.02). Observe the number of decimal places in the number and number of decimal places in the cube of the number. Is there any relation between the two?

Answer 1

the cube of (0.02) = 0.000008
the decimal place in the no. is 2 but in the cube is 6
so we can say that if we will cube it or square it the decimal place will increase with the original no.

Answer 2

Answer:

0.000008

Step-by-step explanation:

In this question

We have to find the cube of the number (0.02)

Cube of 0.0.2 = 0.02 × 0.02 × 0.02

Cube of 0.02 = 0.0004 × 0.02

Cube of 0.02 = 0.000008

Decimal place in the number = $2\times 10^{-2}$

Decimal place in the cube of the number = $8\times 10^{-6}$

The relationship between the number and cube of the number is $=\ 8\times 10^{-6}\ =\ 2\times 10^{-2}\times 4\times 10^{-4}$

I.e cube of the number is $\mathbf{4\times 10^{-4}}$times the given number
