If `(m+n)/(m-n)=7/3` then `(m^2-n^2)/(m^2+n^2)=`

if m+n=5 and mn= 6, but (m^2 + n^2) (m^3 + n^3) = how much?

Simplify : (m^2-n^2)/((m+n)^2)xx(m^2+mn+n^2)/(m^3-n^3)

If (m + n)/(m + 3n) = (2)/(3) , find : (2n^(2))/(3m^(2) + mn) .

If (7m+2n)/(7m-2n)=5/(3) use properties of proportion to find (i) m:n (ii) (m^(2)+n^(2))/(m^(2)-n^(2))

5m -n = 3m+4n then find the value of the expressions: (m^2+n^2)/(m^2-n^2)

If a^m .a^n = a^(mn) , then m(n - 2) + n(m- 2) is :

If m and n are distinct natural numbers, then which of the following is/are integer/integers? 1. (m)/(n) +(n)/(m) 2. mn ((m)/(n)+(n)/(m)) (m^(2)+n^(2))^(-1) 3. (mn)/(m^(2)+n^(2)) Select the correct answer using the code given below.

If (4m + 3n)/(4m - 3n) = (7)/(4) use properties of proportion to find : (i) m : n (ii) (2m^(2) - 11n^(2))/(2m^(2) + 11n^(2)) .

m^(3)-n^(3)-m(m^(2)-n^(2))+n(m-n)^(2)
