Logarithmic to Exponential Form

Study Guide

Key Definition

If $y = \log_b{x}$, then $b^y = x$ for $x > 0$ and $0 < b \neq 1$.

Important Notes

A logarithm is an exponent.
The base of a logarithm must be positive and not equal to 1.
Logarithms and exponential functions are inverse operations.
Logarithmic equations can be rewritten in exponential form.
Understanding logs is key to solving exponential equations.

Mathematical Notation

$\log_b{x}$ is the logarithm of $x$ with base $b$

$+$ represents addition

$b^y$ is $b$ raised to the power of $y$

Remember to use proper notation when solving problems

Why It Works

By converting logarithms to exponential form, you simplify equations to make solving easier. The expression $y = \log_b{x}$ becomes $b^y = x$, making it easier to evaluate or solve for unknowns.

Remember

Always check that the base $b$ is greater than 0 and not equal to 1 when working with logarithms.

Quick Reference

Exponential Form:$b^y = x$

Logarithmic Form:$y = \log_b{x}$
