SL Core 1.5
Logarithms are a mathematical tool for asking "what power of a given base gives a specific value". We write this as
Here, a is called the base, and must be positive. The value of x, however, can be any real number.
Examples
log5125 means "what power of 5 makes 125". Since 53=125:
log3(91) means "what power of 3 makes 91". Since 91=321=3−2:
