Answer 1

I hope this helps you



-2a^2b.4.a^5.b^2



-8.(a^2+5)(b^1+2)



-8.a^7.b^3

Answer 2

The correct option is A)
`-8a^(7)b^(3)`.

Explanation:

Consider the provided expression.

`(-2a^2b) \cdot (4a^5b^2)`

Now open the parentheses.

`(-2*4)(a^2* a^5)(b* b^2)`

Now, use the product rule:
`a^m \cdot a^n= a^(m+n)`

`(-8)(a^(2+5))(b^(1+2))`

`(-8)(a^(7))(b^(3))`

`-8a^(7)b^(3)`

Hence the simplified form of the provided expression is
`-8a^(7)b^(3)`.

Therefore, the correct option is A)
`-8a^(7)b^(3)`.
