Please help me solve this.

Solve for y in terms of x:log2x+log2y=1

This is all i have so far: log2xy=1 and log2 rewrites as b^p=n

So, b=2 p=1 and n=xy
What do i do after this? There are three consecutive even intergers. If twice the first integer added to the second is 268,262,find al three integers.
