Question

MEDALS if you help me!!! help please! :) simplify the following expressions:
1. (4p^1/4q^-3)^1/2
2. (5b)^-1/(8b^6)^1/3
3. (2x^6y^8)^1/4 x (8x^-2)^1/4
4. (m^1/3n^1/2)^2 x (m^1/6n^1/3)^4 x (mn)^-2

Answer 1

1. the 4's in the parentheses will cancel and you can move the q^-3 up to get (pq^3)1/2
which then gives p^1/2 times q^3/2

Answer 2

where are you stuck?
to complete these questions you can either use the radical expression or first reverting the indexes to positive.
