I rewrote all 8s as 2^3 early on thinking it would simplify. At the end I got 2^(21/8) which I guess is the same as 8^(7/8) if you again rewrite as 2^3=8 by factoring the 21=3×7.

If you rewrite the square root to the power with exponentt 1/2, you can simply apply the rules a=a^1 and a^n*a^m=a^(n+m) to dothe calculation .... You may simplify the result by applying (a^n)^m=a^(n*m) and 8=2^3.
