Question

Can anyone explain this to me? -Thanks

prov · Answer

is there any mistake in the question? either in question or answer
because I have tried to plug in number and it doesn't work

i.e. i use x=2 and y=1/2 then result = 25/9
if i use x=3 and y=1/3 then result = 25/16

or else it might be my mistake

sreehari · Answer

I think the question is asking for 2^(x+y)^2/2^(x-y)^2 = 2^(4xy) = 2^4 = 16

yeah, I thnk so
if the question is like this, sreehari has made a point

sreehari · Answer

This question was posted in the past on this forum, and that's how remember that the question is asking for exponent. It's pretty obvious that the question doesn't make sense as it is (like 2 in both numerator and denominator), but again it's interesting to see how the format could be messed during a screen capture!

The correct question is 2 ^ ((X+Y)^2) / 2 ^ ((X-Y)^2)
