Question

What is `-4b^3*2b^5`?

Answer 1

-8b^8

Explanation:

`-4*b^3*2*b^5`
We can split this up to be
`(-4*2)*(b^3*b^5)`

That's not a necessary step, but grouping factors helps me understand what's going on :)

Because the bases are the same (they're both `b`) and multiplying, we just add the exponents

`-8*b^8`
`-8b^8`
