Ok I hope I write this out correctly:
One of the expressions below is almost equivalent to (5a^2b)^2/5 and would be the same if we restrict the domain slightly, identify which one and explain why:
a). 5^2/5 a^1/5 b^2/5
b). square root of (5a^2 b)^5
c). 2a^4/5 b^2/5
d). (5^2/5 b^2/5)/(a^-4/5).
I am not sure how to begin this...I don't know what he means by restrict the domain slightly...any help? Thanks!
