What is a logarithm?

Logarithms are another way of thinking about exponents.

For example, we know that \blueD22start color #11accd, 2, end color #11accd raised to the \greenE4^\text{th}4

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
