Exponential equation
from class: College Algebra Definition An exponential equation is an equation in which the variables appear as exponents. These equations often take the form $a^{x} = b$ where $a$ and $b$ are constants.
congrats on reading the definition of exponential equation . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test Exponential equations can be solved by taking the logarithm of both sides. If bases are the same on both sides of the equation, their exponents can be set equal to each other. Natural logarithms (ln) are often used when solving exponential equations involving base $e$. Graphing can help visualize solutions to some exponential equations, particularly those with multiple or complex solutions. Changing the base using logarithmic properties can simplify solving certain exponential equations. Review Questions How do you solve an exponential equation where the base is not easily converted? What property allows you to equate exponents when bases are identical on both sides of an exponential equation? Which logarithm is typically used when dealing with base $e$ in an exponential equation? "Exponential equation" also found in:
