If n is a positive integer, then find int x^n dx

Solve (x - 1)^n =x^n , where n is a positive integer.

Solve (x-1)^(n)=x^(n), where n is a positive integer.

If n is a positive integer and u_(n)=int x^(n)sqrt(a^(2)-x^(2))dx

If ((1+i)/(1-i))^x=1 then (A) x=2n+1 , where n is any positive ineger (B) x=4n , where n is any positive integer (C) x=2n where n is any positive integer (D) x=4n+1 where n is any positive integer

If n is a positive integer and n in[5,100] then the number of positive integral roots of the equation x^(2)+2x-n=0 is

If lim_(x rarr 2) (x^n-2^n)/(x-2)=80 and if n is a positive integer, find n.
