Monomials

I have two problems that I have done but I am not sure they are correct.

1) t^-5(t^2-t^4+5t) I got... 5t/t^7

2) -20(m^2v)(-v)^3 / 5(-v)^2(-m^4) I got.... 20(4v^2)/ 5m^2

  1. You have to be much more specific regarding the order of operation here, use brackets please
    e.g. you have 3 terms inside the bracket in the first question, but your answer is a single term, not very likely.
