Can someone please explain its solution to me?
I did ๐ x 10^-2 = (๐^2)^4
So it doesnโt seem to work.
First of all itโs quadruple which means multiplied by 4, your answer is correct as x <> 0, so x = 1/400. You can try it in reverse order also, just substitute 0.0025 as x in following eqn: x/100 = 4(x^2) which equals to 0.000025.
