# Make y the subject off y=(x-2)^3 watch

1. Make y the subject off y=(x-2)^3???

how do you do this people. This is a smaller part of a bigger question so just a quick explanation will do. If you know how to do it just tell me how if that is quicker rather than showing.

Edit: im an idiot this is simple it just clicked after i made the thread lol
2. y is already the subject of that equation. Do you mean make x the subject?
If so, (cuberoot)y=x-2
(cuberoot)y+2=x
3. Isnt 'y' already the subject?

isn't y already the subject of the formula???

if you meant make 'x' the subject of the formula then we can do it.

the opposite of cubed is to take the third root

so it will be ³√y = x-2

therefore x = ³√y + 2
