It is known that the m-2n power of negative two X is the same as the 4-m power of half times the 5th power of x times y. find the algebraic formula (m-2n) ^ 2-5 (M + 2n) ^ 2 + m + n Value of

The m-2n power of negative two X is the same as the 4-m power of half times the 5th power of x times y,
Then m-2n = 5,4-m = 0
Then M = 4, n = - 1 / 2
(m-2n)^2-5(m+2n)^2+m+n
=(4+1)^2-5(4-1)^2+4-1/2
=25-45+4-1/2
=-16 and 1 / 2
