does anyone know how to multiply (2x-1 )cubed/(2x-1)^3

yes think about it if x is cubed you multiply it by x 3 times so x times x times x

so say x = 3 3 cubed is 27

now lets say we have (x-10)squared what do you do? (x-10)(x-10) = (x-10)^2

the same logic follows a quantity being cubed

hope I was clear enough

I think someone is pulling their leg: something divided by itself =1

Pretty sure the / was to separate the two different ways to write quantity cubed

Yes, I agree with james.

It just means (2x-1)(2x-1)(2x-1).

You just need to sort out the first 2 brakets first, then do the 3rd set once you've simplified that.
