The Attempt at a Solution



tried:
sin2x formula
writing 1-cos^2 instead of sin^2x
letting u=sinx
letting u=cosx

no luck yet

recall that
[sin(x)]^2[cos(x)]^4=(2+cos(2x)-2cos(4x)-cos(6x))/32
or recall that
[sin(x)]^2[cos(x)]^4=(A+B cos(2x)+C cos(4x)+D cos(6x))/32
for some numbers A,B,C,D and deduce such numbers
or integrate by parts
or make us of trigonometric reduction formula

thank you for your answer. this question seems to be too long but i managed to solve it.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
