Question 319265: Please help with this question: I have the answer but cannot figure out how to get it. thanks

Solve for x, (1 + x)3.2 = 8.4
[x = 0.9446

You can put this solution on YOUR website!
(1+x)3.2=8.4
which means 3.2*1 + 3.2*x=8.4
now subtract 3.2 from both sides of the equation,so that we only have the term involving 'x' on the left hand side of the equation(LHS).
Therefore 3.2*x=5.2
now divide both sides of the equation by 3.2 so that we only have 'x" on the LHS.
Thus x=5.2/3.2=1.65625
