Solve for q:
q^5 = 8 sqrt(2)

Taking 5^th roots gives 2^(7/10) times the 5^th roots of unity:
Answer: |    q = 2^(7/10)

Q^5 = 8sqrt2 = 8 (1.414)

Q^5 = 11.31    Then take the 5th root of both sides to get 'Q'  (see instructions below)

Q=1.6243

on Web2.0 calc enter    11.31 then the ' y checkmark x'   key,   then 5   then =

 q^5=8sqrt(2) square both sides,

q^10=64 X 2

q^10=128

q^10=2^7 taking the 10th root of both sides we have,

q=2^(7/10)
