Solving Exponential Equations and Logarithms

The video tutorial covers solving exponential and logarithmic equations. It begins with solving exponential equations using common bases, explaining how to equate exponents when bases are the same. The tutorial then transitions to solving equations that cannot be rewritten with common bases by using logarithms, demonstrating the conversion to exponential form and using tools like Desmos for calculations. The instructor encourages practice beyond the tutorial for mastery.

What are the two basic methods to solve exponential equations?

• Using a common base and converting to logarithmic form

• Using a calculator and guessing

• Graphing and using a common base

• Trial and error and converting to logarithmic form

When solving exponential equations with a common base, what is the first step?

• Add the exponents

• Subtract the exponents

• Find a common base for the exponents

• Divide the exponents
