Explanation.
0.1^3+0.2^3/0.2^3+0.4^3 look here,
.04^3 means.0.2^3*0.2^3.
So, 0.1/2^3.
0.1^3+0.2^3/0.2^3+0.4^3 look here,
.04^3 means.0.2^3*0.2^3.
So, 0.1/2^3.

Friends its very simple first remove decimals then you get.
(1^3+2^3/2^3+4^3) = 1+8/8+64 = 9/72 = 1/8.
Dividing you get 0.125.
(1^3+2^3/2^3+4^3) = 1+8/8+64 = 9/72 = 1/8.
Dividing you get 0.125.

(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.

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.

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

We take root of 1/8,
Then we get the answer 0.125.
Then we get the answer 0.125.

Here
2 * (0.1) = 0.2
2 * (0.02) = 0.04
Then the question we get;
(0.1)^3 + (0.02)^3 / (2(0.1))^3 + (2(0.02))^3.
Then the denominator we can take 2 in common,
(0.1)^3 + (0.02)^3 / 2^3[(0.1)^3 + (0.02)^3].
Then, we can get 1/2^3.
We know 1/8, So we get the answer is 0.125.
2 * (0.1) = 0.2
2 * (0.02) = 0.04
Then the question we get;
(0.1)^3 + (0.02)^3 / (2(0.1))^3 + (2(0.02))^3.
Then the denominator we can take 2 in common,
(0.1)^3 + (0.02)^3 / 2^3[(0.1)^3 + (0.02)^3].
Then, we can get 1/2^3.
We know 1/8, So we get the answer is 0.125.
