Im having difficulties in algebra when solving this problem.
Homework Equations
The Attempt at a Solution
[tex]\int_-1^1 (x^4/3 + 4 x^1/3) dx [/tex] = 3/7 (1)^7/3 + 4 3/4 (1)^4/3 - 3/7 (-1)^7/3 + 4 3/4 (-1)^4/3
= 3/7 + 3 - (-3/7 +3) = 6/7
Im having difficulties computing 3/7 (1)^7/3 and 4 3/4 (1)^4/3
since 1^ 7/3 = 1/3 and 3/7 1/3 = 1/ 7 and tahts not the answer on the book
and (1)^4/3 = 1/3 and that's not right either.
Thanks in advance
