Question

Simplify

-4x^3 * 2y^2 * 5y^5 * x^8

Answer 1

using the associative property of multiplication you can make this into
\[\huge (-4*2*5)*(x^3 * x^8) * (y^2*y^5)\]
just simplify it from here
remember
\[\huge x^m * x^n = x^{m+n}\]

Answer 2

4x^3 * 2y^2 * 5y^5 * x^8

Arrange them first
x^ 8 * 4x^3 * 5y^5 * 2y2

simply
factoring out by grouping
