In other words 4 to the power of what gives me 17. Well that's not easy to answer. But I do know that 4 squared gives me 16.

The answer lies in your data value range. Log base 10 for a large data range. Log base 2 for data of two powers of 10 or less. Log base e (natural log) for small changes in percentage.

In comparison of two numbers, logarithm of smaller number is smaller, if base of the logarithm is greater than one. Logarithm of smaller number is larger, if base of logarithm is in between zero and one.

Which logarithm is bigger? - YouTube YouTube Start of suggested clip End of suggested clip But here's a trick that saves the day. So 81 over 125 that's roughly 80 over 120. Which is two-MoreBut here's a trick that saves the day. So 81 over 125 that's roughly 80 over 120. Which is two-thirds. And in fact you can check that each fraction is less than two-thirds.

Here are the most commonly used log formulas. logb 1 = 0. logb b = 1. logb (xy) = logb x + logb y. logb (x / y) = logb x - logb y. logb ax = x logb a. logb a = (logc a) / (logc b)

If a > 1 then the logarithmic functions are monotone increasing functions. That is, log a x > log a z for x > z. If 0 < a < 1 then the logarithmic functions are monotone decreasing functions.

This log is eight feet long so she's going to find the eight on her scaling stick.
