1. The problem statement, all variables and given/known data Hi guys, I'm getting confused trying to manipulate an expression. Any help here would be hugely appreciated. How do I manipulate the expression -4 / (4x + 1)1/2 to become (1/4 + x)-1/2 3. The attempt at a solution I've tried dividing by -4 to get and used an index law to get (1/2)*(x+1)-1/2 but that's clearly not the expression I want. I'd really appreciate if someone could point me in the right direction. Thanks in advance.
