If `.^(m+n)P_(2)=90 and .^(m-n)P_(2)=30`, find the value of m and .

If .^(m+n)P_2=72 and .^(m-n)P_2=6 ,then find the values of m and n.

If ^(m+n)P_2=90 and ^(m-n)P_2=30 find m and n

(m+n)P_(2)=56,^(m-n)P_(2)=30 then

If m and n are +ve integers such that (m+n)P_(2)=90 and m-np_(2)=30, the number of ordered pairs (m,n) of such integers is

IF ""^((m+n))P_(2) =90 ,""^((m-n))P_(2) =30 then (m,n)=

If P(m+n, 2) = 56 and P(m-n, 2) = 12 then the values of m and n are

If m = 3 and n = 2 find the value of m^n-n^m
