Question

How do you multiply `(- 12x ^ { 4} ) ( - 2x ^ { 5} )`?

Answer 1

See a solution process below:

Explanation:

First, rewrite the expression as:

`(-12 * -2)(x^4 * x^5) => 24(x^4 * x^5)`

Now, use this rule of exponents to complete the multiplication:

`24(x^color(red)(4) * x^color(blue)(5)) => 24x^(color(red)(4) + color(blue)(5)) => 24x^9`
