Question:

what is greater 1999^{1997} or 1997^{1999}. please explain the steps.

thanks

Hi Rajesh,
Are you a calculus student? If so, the easiest solution is to take the
lagarithm of both sides of a^{b} ? b^{a} and notice that the problem reducuces
to determining whether the function ln x / x is increasing or decreasing
when x = 1997.

Cheers,

Chris
