What is the smallest integer k for which 64k>414?
选项
A、4
B、5
C、6
D、7
E、8
答案
B
解析
If we don’t want to do a lot of calculations, we’re going to have to manipulate the exponents. The first step is to put the 64 and the 4 in the same terms, so let’s make the 64=43 instead. Now the question is looking for the smallest integer k for which 43k>414, which is the same as finding the smallest integer k for which 3k>14. The best answer is 5, or B.
