If m times the mth term of an AP is equal to n times its nth term, then show that (m + n)th term of an AP is zero.

If m times the m^(t h) term of an A.P. is equal to n times its n^(t h) term, show that the (m+n)^(t h) term of the A.P. is zero.

If m times the m^(t h) term of an A.P. is equal to n times its n^(t h) term, show that the (m+n)^(t h) term of the A.P. is zero.

If in an A.P. the sum of m terms is equal of n and the sum of n terms is equal to m , then prove that the sum of -(m+n) terms is (m+n) .

If in an A.P. the sum of m terms is equal to n and the sum of n terms is equal to m then prove that the sum of (m+n) terms is -(m+n)

If a ,\ m ,\ n are positive integers, then {root(m)root (n)a}^(m n) is equal to (a) a^(m n) (b) a (c) a^(m/n) (d) 1
