# simplifying this expression watch

1. how would you simplify this?
would the 4t become 4t^-1 or does the 3t^2 become 3t^-1?

let's carry on with what you have, so we can cancel 1 t from the top and the bottom right?

then i guess that's the simplest form for now, it depends how you want to write it

so [4(1+5t^2)] / 3t^-1? and then laws of indices apply etc?

No - where are you getting 3t^-1 from?

if you want to make a minus power remember that

cos 4t/3t^2 = 4/3t^-1?
7. (Original post by ihatePE)
cos 4t/3t^2 = 4/3t^-1?
No, it isn't.

It is however true that

If you think what you wrote is equivalent to the 2nd expression, refer to the Asking Questions Guidelines and in particular the section on ambiguous expressions.

o i see how its supposed to be that now
9. expand it.
times it by 3t^2
minus 3t^2
then simplify

- what I would do... but probably wrong.

to clarify the simplest expression is [4(1+5t^2)] / 3t ?
