Given problem = [(0.1)^3+(0.02)^3]/[(0.2)^3+(0.04)^3].
Then [(0.1)^3+(0.02)^3]/[(2(0.1))^3+(2(0.02))^3.
Then [(0.1)^3+(0.02)^3]/2^3[(0.1)^3+(0.02)^3].
Then 1/2^3.
Finally 1/8.
Then [(0.1)^3+(0.02)^3]/[(2(0.1))^3+(2(0.02))^3.
Then [(0.1)^3+(0.02)^3]/2^3[(0.1)^3+(0.02)^3].
Then 1/2^3.
Finally 1/8.

Actual answer is 0.017730666.
Then how is possible 1/8 = 0.0025.
Then how is possible 1/8 = 0.0025.

We know the formula, (a^m x b^m) = (ab)^m. In the denominator, take 2^3 common & apply above formula.

Here,
2*[0.1] = 0.2.
2*[0.02] = 0.04.
Thus taking 2 common.
==> 23 [(0.1)3 + (0.02)3].
2*[0.1] = 0.2.
2*[0.02] = 0.04.
Thus taking 2 common.
==> 23 [(0.1)3 + (0.02)3].

First answer is good one we must take the common 2 so we can get the answer essay.

If you calculate with calculator than is the answer is same ?
Can anybody explain it in simple way.

Hai friends,
They just take 2 common in denominator. (0.2)^3+(0.4)^3 they take 2^3 common. So, 2^3(0.1)^3+(0.2)^3.It is cancelled. 1/8 = 0.125.

It simple guys.
Just divide (0.1) hole power 3 and (0.02) hole power 3 and take cube of 2 so we get the answer 1/8.

It is just take the common of 0.2 on denominator.
