# Indices question watch

1. I am getting myself completely muddled on a question, is there any chance someone could go through the method if i give the question?

anyway its this

X= {(S^1/3)^3/4} x {(T^1/4)^-1}
-------------------------------
{(S^-1/4)^-1} / {(T^1/2)^4}

its a big complicated mess trying to type it on a computer, anyway the dashes are meant to symbolise a divide, the top 2 divided by the bottom 2, the 2 on the top are multiplied and the 2 on the bottom of divided.

anyways dunno if anyone will, bit cheeky, but its proper confusing me...

if anyone has this book this is K.A.STROUD FOUNDATION MATHEMATICS, page 81 unit 7...
2. Start by using the rule :

Notice that this is the same as

Notice that the s cancel. This leaves you with:

which you should be able to simplify.

i was using the rule where if its to the power minus 1 that means it should be 1 over the number.... and it was confusing me totally..

nevermind, thanks a lot anyway!

by the way, how do you write the formulas like you have done?
4. Your way was probably correct as well but when you have a long, complicated expression to simplify, it can be easy to get muddled and make mistakes. To write the formulas, there's some instructions on http://www.thestudentroom.co.uk/wiki/LaTeX and you could also click the Quote button next to my post to see the code I used.

If you are dealing with fractions to the power minus 1 then simply invert the fraction.
