Question 58555
a) Using a calculator, find log 1000 where log means log to the base of 10. 
Answer:
Actually, you can do this without a calculator. log(x) = y means: x = 10^y
1000 = 10^y ? ~> answer: 3
b) Most calculators have 2 different logs on them: log, which is base 10, and ln, which is base e. In computer science, digital computers are based on the binary numbering system which means that there are only 2 numbers available to the computer, 0 and 1. When a computer scientist needs a logarithm, he needs a log to base 2 which is not on any calculator.
To be honest, you don't need to change the base. The base 10 returns to 10 due to log(10) = 1.0
log(1000^(1/2))
(1/2)*log(1000)
(1/2)*3
1.5 or 3/2
