Question

in the expansion (x- 1/6)^6 the constant term is 
1.-20
2. 20 
3.30
4.-30

Answer 1

Constant term in the expression has x raise to the power 0
So
            (x-1/6)raise to 6 has x raise to  0 in the last term of the polynomial expression which is term 7
       term 7 = (-1/6) raise to power 6 = 1/46656
May be the options are wrong
