yea 32 As the series is infinite it can only converge if -1 < x < 1

By the ratio test, it follows that the series converges for |x|<1, diverges for |x| > 1.
i read this from forums.....now having read tthis ......do u get any idea on validity cos i dint still get it why we wud want it to cnverge or diverge

A 'Permutation and Combination' problem
Eight cards are selected from a pack of 52 cards, with 12 picture cards, 20 odd cards and 20 even cards.
How many sequences of eight cards will contain 3 picture cards, 3 odd numbered cards and 2 even numbered cards??

Put x = 3^y and u'll get the eqn similar to the one above...!

u know the values of x ...so put 3^y = that value...
2 of them can not be solved...find the answer..
27^y = (3^3)^y =3^3y = x^3
thanks a lot:)
