Why is middle school-grade problem is called olympiad?

let u=2^x , u^3 + u^2 + u - 39=0 , (u-3)(u^2+4u+13)=0 , u=3 , u^2+4u+13=0 , +1 -3 u=(-4+/-V(16-52))/2 , u=(-4+/-V(-36))/2 , u=(-4+/-i*V(36))/2 , +4 -12 u= 3 , / -2+3i , -2-3i /, 2^x=3 , x=log3/log2 , test , x=log3/log2 , +13 -39=0 , 2^(log3/log2)+4^(log3/log2)+8^(log3/log2)=3+9+27 , --> 39 , OK
