Question

Simplify (8x^4)(4x^3)/7x^2.

Answer 1

The idea is to multiply and divide the coefficients of terms and add and subtract the powers of the variable "x"

Here is it:

8*4/7 = 32 / 7

and


`(x^4 * x^3)/(x^2) =x^(4+3-2)=x^5`

So, we can write the final form as follows:


`(32x^5)/(7)`


which leads us to the choice A


Hope that helps
