I need help simplifying [(A+1)^(1/3)]-{[(A+1)^(-2/3)]*(A-1)}
Easier to the eye: (A+1)^1/3 - [ (A+1)^-2/3 * (A-1) ]
It has been 4 years since I took this stuff. Thanks!
Multply the first term by (A+1)^2/3 , both numerator and denominator.
That will leave you an (A+1)^2/3, in the denominator.
Now, factor out that 1/(A+1)^2/3 term in the first and second terms, and combine the numerators.
