The distance between the points (m,-n) and (-m,n) is (A) sqrt(m^2 + n^2) (B) m+n (C) 2 sqrt(m^2+n^2) (D) sqrt(2m^2 +2n^2)

The distance between the points (m,-n) and (-m,n) is (A) sqrt(m^2 + n^2) (B) m+n (C) 2 sqrt(m^2+n^2) (D) sqrt(2m^2 +2n^2)

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)) .

Find the value of the products: (3m-2n)(2m-3n)a t\ m=1,\ n=-1

Simplify each of the products: (m+n/7)^3\ (m-n/7)

If tan theta+sin theta=m and tan theta-sin theta=n , then (a) m^2-n^2=4m n (b) m^2+n^2=4m n (c) m^2-n^2=m^2+n^2 (d) m^2-n^2=4sqrt(m n)

Find the value of m and n : if : ( 3+ sqrt2 )/( 3- sqrt2) = m + n sqrt2

The product of (3m^2n^7(-4m^4n^3) is equivalent to :
