Just simply take 2^3 as common in the denominator.
(0.1)^3 + (0.02)^3/2^3(0.1^3+0.02^3),
= 1/2^3 = 1/8,
= 0.125.
(0.1)^3 + (0.02)^3/2^3(0.1^3+0.02^3),
= 1/2^3 = 1/8,
= 0.125.

0.1X0.1X0.1/((2X0.1)+(2X0.1)+(2X0.1) and so on;
Hence 1/2^3 that is 0.125.
Hence 1/2^3 that is 0.125.

2((0.1)^3 + (0.02)^3) = (0.2)^3 + (0.04)^3 why do we have to take 2^3 out of it?

0.2 = 2/10 = 2 * (0.1).
And 0.04 = 4/100 = 2(2/100) = 2 * (0.02).
Taking 2 in common, expression can be written as given explanation.
And 0.04 = 4/100 = 2(2/100) = 2 * (0.02).
Taking 2 in common, expression can be written as given explanation.

(0.1)^3+(0.2)^3=0.9 /(0.2)^3+(0.4)^3 = 0.70,
So, 0.9/0.70 = 0.125.
So, 0.9/0.70 = 0.125.

By dividing 1/8=0.125.

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].
