For natural numbers `m ,n ,if(1-y)^m(1+y)^n=1+a_1y+a_2y^2+ ,a n da_1=a_2=10 ,t h e n` `m n` c. `m+n=80` d. `m-n=20`

For natural numbers m,n, if (1-y)^(m)(1+y)^(n)=1+a_(1)y+a_(2)y^(2)+... and a_(1)=a_(2)=10 then (A)m n(C)m+n=80(D)m-n=20

For natural numbers m, n if (1-y)^(m)(1+y)^(n) = 1+a_(1)y+a_(2)y^(2) + "……." and a_(1) = a_(2) = 10 , then (m,n) is :

For the natural number m, n, if ( 1- y ) ^(m) (1 + y) ^( n) =1 + a _(1) y + a _(2) y ^(2) + ...+ a _( m + n) y ^( m +n) and a _(1) = a _(2) = 10, then the value of (m+n) is equal to :

If m and n are degree and order of (1+y_1^2)^(2//3) = y_2 , then the value of "m+n"/"m-n" is

If x^m y^n = (x+y)^(m+n) then find (dy)/(dx) at x=1, y=2

If m ,n in Na n dm^2-n^2=13 ,t h e n(m+1)(n+1) is equal to a. 42 b. 56 c. 50 d. none of these
