2lan(3) = 2.1972 [ lan is short for natural logarithm or log to the base e where e=2.71828...]
Place a decimal between 2 & 3. It will become 2.3
Thus 2 < 2.3 < 3
Hence, a "decimal" is the answer.
Place a mathematical symbol between the numerals 5 and 9 in such a way that the resulting number is greater than 5 but smaller than 9.
