Carrying out the required process in the left hand sign of the equation,
(2/20x^3) = 10^7
(1/10x^3) = 10^7
Solving for x^3,
x^3 = 1/10^8
IF, however, your original function looks like this
(1/4)x * (2/5)x = 10^7
0.1x^3 = 10^7
x^3 = 10^8
******************************
So, depending on how your original function really looks like, you have two choices for your answer. Only one is the correct answer though! I am sure you can solve for "x" from here.

1/4x • 2/5x^2= 10^7
Is this: 1/(4x) times 2/(5x²) = 10^7 ?
2/(20x³) = 10^7
1/(10x³) = 10^7
1 = 10x³ × 10^7
1 = (10^8)x³
1/(10^8) = x³
cuberoot1 / cuberoot(10^8) = cuberoot(x³)
1/(100cuberoot(10²)] = x

0.25x * 0.4x^2 = 10,000,000
0.1x^3 = 10,000,000
x^3 = 100,000,000
x = 464.16
this is your problem i cant solve it for you!!!!!
buti help. start with 10 to the 7th and then ur on ur own. just simplify it.
