Use the logrithm table to find the log of these numbers (a)900(b)4620(c)12.34

Answer 1

The log table gives the logs of numbers from 1-9.9999 or something
Now note that since
900 = 9 * 10^2
then
log900 = log9 + 2
so look up log9 and add 2

log4620 = log 4.62 + 3
and so on

Answer 2

ANSWER 4620 - 4.62 =2.859
