Problem: If one uses only the tabular information 103=1000,104=10,000,210=1024, 211=2048,212=4096,213=8192, then the strongest statement one can make for log102 is that it lies between:
Answer Choices:
A. 103 and 114
B. 103 and 124
C. 103 and 134
D. 103 and 18240
E. 113 and 13240
Solution:
Since 210=1024>103=1000,10log102>3 so that log102>103. Since 213=8192<104=10000, 13log102<4 so that log102<134.
