So here, b=1/2. Find c such that this equation simplifies.
For example, c=2.
This will give : ![Z^2=\left([A(1+x)]^{1/2} \right)^2](http://www.mathhelpforum.com/math-help/latex2/img/c372507d19b5ce656473f792b8a1f831-1.gif "Z^2=\left([A(1+x)]^{1/2} \right)^2") ![Z^2=[A(1+x)]^1=A(1+x)](http://www.mathhelpforum.com/math-help/latex2/img/46247110b7611f4b508ebc1f10428381-1.gif "Z^2=[A(1+x)]^1=A(1+x)")
Can you continue ?
