Re: If x and y are positive integers, what is the value of xy?

IMO 4



from 1 statement

256 = 2^8

so x^2+y^2 = 8


from statement 2 we get

2^(x^2 -y^2) = 2^0

x^2 - y^2 = 0

so it means x-y = 0 becauae x and y are positive integers

so put x= y in first statememt we get x = 2

so y = x = 2

so xy = 4
