Question

simplify: (2ab^2)(-5a^(-4)b^5

Answer 1

(2ab^2)(-5a^(-4)b^5
\[= (2)(-5)a^{1-4}b^{2+5}\]
= ..?
Note: \(a^{-n} = \frac{1}{a^n}\)

Answer 2

-10a1/4b^7???

Answer 3

Nope, not really.
What is 1-4?

Answer 4

-3

Answer 5

So,
\(=-10a^{-3}b^7\)
You need to know that \(a^{-n} = \frac{1}{a^n}\)
By this, we can get
\(=\frac{-10b^7}{a^{3}}\) Got it?

Answer 6

yessss
