I keep getting 4 as answer for this; the answer is 16 can someone explain what I am missing
original question
DS
x*y=1
2^(x+Y)^2/2^(x-y)^2
THanks

You were doing this (highlighted in Red) which is wrong
2^(2.5)^2/2^(1.5)^2
2^5/ 2^3
2^(5-3)
2^(2)
4

Correct solution is this.
2^(2.5)^2/2^(1.5)^2
2^6.25/ 2^2.25
2^(6.25-2.25)
2^(4)
16

Hope this helps
