Beginning with...
(1/2y5)3
Both the numerator and denominator must be raised to this exponential.
13=1
(2y5)3
23=(2)(2)(2)=8.....(y5)3=y15
(1/8y15)
 
(2y2)4
24=(2)(2)(2)(2)=16.....(y2)4=y8
(16y8)
 
It is now...
(1/8y15)(16y8)
Let's combine and simplify...
16y8/8y15
16/8=2.....subtract exponents, 8-15=-7
2y-7  or  2/y7
