Re: 6( 10) n > 60,006 [#permalink]

This is basically a simple problem where they want to see if you get tripped up by forgetting that, since there is an inequality, n will be ANY number greater than or equal to the first n value that puts the left side above the right. n=4 gives 60,000. n=5 gives 600,000 (the first value above 60,006). Therefore the MINIMUM value for n is 5 while the greatest is "infinite answers." Since B is 6, n=5 gives A<B, n=6 gives A=B, and n=7+ gives A>B...all being possible answers. The answer is therefore clearly D.

6* (10^n) > 6* (10^4) + 6 n>4 or n>=5 So n should be at least 5, it can be 5, 6, …. So the answer is D because it might be 5 and less than 6, equal to 6 or even more than 6.
