If the coefficient of 5^(th) and 3^(rd) terms in the expansion of (sqrt(15/2)x + 1/x^2)^n where n in NN are equal, then the term independent of x is (A) 5th (B) 4th (C) 6th (D) 7th
If 6th , 7th , 8th, and 9th terms of (x+ y)^n are a,b,c and d respectively , then prove that : (b^2 - ac)/(c^2 -bd) =4/3. a/c
AC schedule of a firm is given. Calculate the firm's MC for (i) 6th and (ii) 7th units,
The 7th term of an AP is -1 and its 16th term is 17. The nth term of the AP is
If the 6th,7th, 8th terms in the expansion of (x+y)^(n) be 112,7 and 1/4 find x,y and n.
