hot to integrate the following:

(x¹⁰ - 1) divided by (x - 1)

x raise to power n - y raise to power n [xn-yn]

=(x-y) (x raise to power n-1 + x raise to power n-2 . y +...............+ y raise to power n-1)

x10-1 = (x-1) ( x9 + x8+................+1)

now (x-1) will be cancelled from (x-1)

and the answer will be the remaining part
