If f(x) = (1 + x) (1 + x^(2)) (1 + x^(4)) (1 + x^(8)) , then f'(1) is

Find the value of ( 1 + 1/x ) ( 1 + 1/( x+1 )) ( 1 + 1/( x+2 ) ) ( 1 + 1/( x+3 )) is : (1) 1 + (1/(x + 4 )) ( 2 ) x +4 ( 3 ) 1/x ( 4 ) ( x+4 )/x

The continued product of (1 + x), (1 + x^2), (1 + x^4), (1 + x^8) and (1 - x) is :

Find the value of : ( x^(1/2 ) + x^(-1/2 ) ) times ( x^(1/4 ) + x^(-1/4 ) ) times ( x^(1/8 ) + x^(-1/8 ) ) times ( x^(1/8 ) - x^(-1/8 ) ) ( a ) x + 1/x ( b ) ( x^2 -1 )/x

What is (8x)/(1-x^(4)) - (4x)/(x^(2) +1) +(x+1)/(x-1) - (x-1)/(x+1) equal to?
