In general if n is a natural `a xx a xx a xx a xx ...xx a = a^n `n - times a^n is called the nth power of a and is a also read as a raised to the n

If 1 xx 2 xx 3 xx …….xx n is denoted by , then is equal to :

Evaluate : ( b ) a^3 times b^3 ( d ) a^n times b^n times c^n times d^n

If A={a,b}. Then n(A times A) is :

Find the whole number for which: n times n =n

If m times the mth term of an A.P. is equal to n times its nth term, find (m + n) th term of the A.P.:

If A is a matrix of order m xx n and B is a matrix such that AB^(T) and B^(T)A are both defined,then the order of matrix B is m xx n (b) n xx n( c) n xx m(d)m xx n
