Logarithms...i need help.
A logarithm of a number is the exponent of the power to which a fixed number. called the base, must be raised to produce the given number.
I absolutely do not understand what these things mean. In my textbook it shows a graph of x=10y.
Then it follows with 6 questions which are as follows:
1. For what values of x do the corresponding logarithms change most rapidly?
2. How does the rate of change of y compare with that of x for values of x between 1 and 10?
3. For what values of x are the values of y negative?
4. What is the approximate value of y when x=8? 15? 28?
5. What is the number whose logarithm is .2? .4? 1.2? 1.4?
6. Show that in the graph log 10 is approximately equal to log 5+log 2; that log 5 is approximately equal to log 25-log 5. that log 27 is approximately equal to 3 log 3.
PLEASE ANSWER BUT EXPLAIN HOW THESE ARE DONE PLEASE...
Thanks.
