Question

How do you multiply `(- a ^ { 3} b ^ { 5} ) ^ { 2} \cdot ( a ^ { 4} b ) ^ { 2}`?

Answer 1

By squaring, the `-`sign will disappear.

Explanation:

We now take the square into the parentheses.
This means multiplying exponents by 2:

`=(a^6b^10)*(aq^8b^2)`

In multiplying we add the exponents:

`=a^(6+8)b^(10+2)=a^14b^12`
