If `(1 + ax)^n= 1 +8x+ 24x^2 +.....` then the value of a and n is

If (1 + ax)^n = 1 + 8x + 24x^2 .... then the value of a and n are

If (1+alphax)^(n)=1+8x+24x^(2)+ . . . , then the value of alpha and n is

If (1 +px)^(n) = 1 + 24x + 264x^(2) + .. . then

The first three terms in the expansion of (1+ ax) ^(n) are 1, 6x and 16x^(2), then the values of a and n are -

If (1+ax)^n = 1 + 8x + 24x^2 + … and a line through P(a, n) cuts the circle x^2 + y^2 = 4 in A and B , then PA.PB =

If (1+ax)^n = 1 + 8x + 24x^2 + … and a line through P(a, n) cuts the circle x^2 + y^2 = 4 in A and B , then PA.PB =

If (1+ax)^n = 1 + 8x + 24x^2 + … and a line through (a, n) cuts the circle x^2 + y^2 = 4 in A and B , then PA.PB = . (A) 4 (B) 16 (C) 8 (D) none of these

If (1 + ax)^(n) = 1 + 6x + 27/2 x^(2) + ...... + a^(n)x^(n) , then the values of a and n are respectively

The first three terms in the expansion of (1+ax)^(n)(n!=0) are 1,6x and 16x^(2). Then find the value of a and n.
