I cannot figure out how to get to the solution of 12/5 for the equation:
2x(4-x)^-1/2 - cube root(4-x)= 0
Sorry, I do not know how to write the cube root.
I tried to write the equation in different ways by using the laws
x^-1/2 = 1/x^1/2
or
cube root(x) = x^1/3
but that does not help me.
Any idea that would help me to get in the right direction?
Thanks
