Question

How do you simplify `(5rs-1t^3)(-3r^2st)`?

Answer 1

`-15r^3s^2t+3r^2st^4`

Explanation:

Did you mean expanding the brackets? Or if you actually meant simplifying, please contact me.

You have to multiply each term in the first bracket by the second bracket.

Note : To multiply 2 terms with powers, add the powers. For e.g. `a^4+a^5=a^(4+5)=a^9`

`5rs*-3r^2st=-15r^3s^2t`

`-1t^3=-t^3`
`-t^3*-3r^2st=3r^2st^4`

`-15r^3s^2t+3r^2st^4`
