Logarithms are exponents that indicate the power to which a base must be raised to yield a given number. For example, the base 10 logarithm of 100 is 2 because 10^2 equals 100. Logarithms are useful for solving exponential equations and are used to measure sound intensity in decibels, earthquake magnitudes on the Richter scale, star brightness, and pH chemistry scales. The decibel is the unit used to measure noise levels and is represented by db.

2. Logarithms
Logarithm, the exponent or power to which a base must be raised to yield a
given number. Expressed mathematically, x is the logarithm of n to the base
b if bx = n, in which case one writes x = logb n.
For example, the base ten logarithm of 100 is 2, because ten raised to the
power of two is 100: log 100 = 2. because. 102 = 100.

3. Logarithms
Much of the power of logarithms is their usefulness in solving exponential
equations. Some examples of this include sound (decibel measures),
earthquakes (Richter scale), the brightness of stars, and chemistry (pH
balance, a measure of acidity and alkalinity).
