Question

Simplify each expression. (–5x2y)(3x4)a. 15x6yb. –15x2yc. –15x6yd. –15x8y

Answer 1

The given expression is

`(-5x^2y)(3x^4)`

We will multiply at first -5 by 3

`-5*3=-15`

Then we will multiply x^2 by x^4 by adding their powers

`x^2* x^4=x^(2+4)=x^6^{}`

And multiply y by 1 as there is no y in the second bracket, then

`(-5x^2y)(3x^4)=-15x^6y`

The answer is C
