What they are: A logarithm is the exponent you raise a base to in order to get a number, acting as the inverse of exponentiation. Why they matter: They simplify multiplication, division, and roots ...

In this math tutorial, we demonstrate how to solve exponential equations using logarithms. We tackle easy, medium, and hard ...

\({\log _a}a = 1\) (since \({a^1} = a\)) so \({\log _7}7 = 1\) \({\log _a}1 = 0\) (since \({a^0} = 1\)) so \({\log _{20}}1 = 0\) \({\log _a}p + {\log _a}q = {\log _a ...

Notably, taking Algebra 1 and 8th grade math together boosted all students’ scores—not just those of students who were less ...
