I’m super confused with the rearranging of this equation:

x = (x-2)^4 /81

into the form x = p + qx^r

where I think p, a and r are integers? but not 100%

any help is appreciated!!!

It can't be done.

Did you mean, into the form x=(p+qx)^r

Ah, just realised, it can be done but r won't be an integer.

You want to rearrange to make the x inside the brackets the subject.
