4^2/4 4^2/5
= 4^(2/4 + 2/5)
= 4^(10/20 + 8/20)
= 4^(18/20)
= 4^(9/10)


7^2/3 divided by 7^1/2
= 7^(2/3 - 2/12)
= 7^(8/12 - 2/12)
= 7^(6/12)
= 7^(1/2)


(t^4/5)^10
= t^(4/5 * 10)
= t^(4 * 2)
= t^8


Seriously, I don't mind feeding askers with the working; after all, I'm at the gaining end.

+2 points!

4^2/4 4^2/5 = 4^(9/10)

7^2/3 divided by 7^1/2 = 7^(1/6)

(t^4/5)^10 = t^8

a^x a^y =a^(x+y)
a^x/a^y = a^(x-y)
(a^x)^y = a^xy
use this and go on you home work!
