Question

14. (2)( (1+x)left(1+x^{2}right)left(1+x^{4}right)left(1+x^{8}right)(1-x) )
( =left(1-x^{2}right)left(1+x^{2}right)left(1+x^{4}right)left(1+x^{8}right) )
( =left(1-x^{4}right)left(1+x^{4}right)left(1+x^{8}right) )
( =left(1-x^{8}right)left(1+x^{8}right) )
( =1-x^{16} )
( quadleft[because(a+b)(a-b)=a^{2}-b^{2}right] )

# ) (1+ ४) (1+ x) (1- ४) 14. (1+ 3) (1+ का मान है। (1) 1+16 (3) x16 -1 (2) 1-16 (4) x + 1
