How to do solve this?
4x^2(5x^4 / 2x^2)

4x^2(5x^4 / 2x^2)= 10 x^4

Step-by-step explanation:

We want factorize the expression 4x^2(5x^4 / 2x^2)

And to do this, we need to remember key properties of exponents.

Those are:

So

4x^2(5x^4 / 2x^2)= 4x^2(5/2 x^2)=10 x^4

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
