Algebra and Power Help... Please!

Hello all, I need help solving the following equation for x:
a = (1-x) ^ {[2/(1+g)]-2}
Can anyone help?
Thank you so much.

Thanks for the prompt response Hoempa - can I just confirm that the denominator and numerator on the right are the correct way round?

If a = 1/4 and g = 1/2, what does your result tell you x is?
