The coefficient of `x^8` in the expasnsion of `(1+(x^2)/(2!)+(x^4)/(4!)+(x^6)/(6!)+(x^8)/(8!))^2` is

If the coefficient of x^8 in the expansion of (1+ (x^2)/( 2!) + (x^4)/( 4!) + (x^6)/( 6!) + (x^8)/( 8!))^(2) is (1)/(M) , then a divisor of M is

The coefficient of x^(4) in the expansion of (1-x-2x^(2))^(8) is

Find the coefficient of x^4 in the expansion of (x^2 - (2/x))^8

The coefficient x^(6) in the expansion (1+x^(2)-x^(3))^(8) is

Find the coefficient of x^7 in the expansion of (1+2x + 3x^2 + 4x^3 + 5x^4 + 6x^5 + 7x^6 + 8x^7)^10

x-(1)/(4)(x-(2-x)/(6))=(2x+8)/(3)-3

coefficient of x^(10) in (1+2x^(4))(1-x)^(8) is:

1/((x-2)(x-4))+1/((x-4)(x-6))+1/((x-6)(x-8))+1/3=0
