Question

What is `(4y^3)(3x^3y^5)`?

Answer 1

`12x^3y^8`

Explanation:

Everything in the second brackets is multiplied by everything in the first brackets.

Dealing with just the numbers we have: `4xx3=12`

Both brackets have `y's` in them so dealing with this we have `y^3xxy^5" "=" "y^(3+5)" "=" "y^(8)`

Putting it all together we have:

`12xxx^3xxy^8" written as "12x^3y^8`
