but googol being 10^100 the n might be generalised solution

is this solution right

480.19<n<481.19 - Apr 1st 2009, 08:30 AMaustinvishalsolution
can you explain me the steps? i made a calculation error i suppose

I agree with austinvishal on this one. Taking logs to base 10 (as we old-timers used to do all the time before they came up with these newfangled electronic thingies), we want to find . So we should take n = 481.
