Re: 2017 Regional no.9 Dhaka
I think the problem can be solved in this way--- 1+2^(4-3m^2-n^2)=2^(k+4-4m^2)+2^(n^2+k-m^2) or,1+2^(4-3m^2-n^2)=2^k(2^(4-4m^2)+2^(n^2-m^2)) or,1+a/b=2^k(a+b) or,(a+b)/b=2^k(a+b) or,2^k=1/b or,2^k=2^(m^2-n^2) or,k=m^2-n^2 Then by solving this equation,I think the answer is 72
