Helllo I have no idea how to do this problem
given f(x) = x3(x + 4)^(1/2)
how to solve for x when f(x) = 5
I know I could just guess and check but I would like to know how to do this algebraically by pluging in 5 like so
5 = x  3 (x + 4)^(1/2)
and solving for x which I don't know how
also is just by luck that 22/7 is pi?????
