Solving Exponential and Logarithmic Equations

The video tutorial covers solving exponential and logarithmic equations. It begins with a review of solving exponential equations by matching bases and progresses to handling cases where bases differ using logarithms. The tutorial includes examples demonstrating these methods and discusses properties of logarithmic equations, emphasizing the importance of checking solutions for validity. The lesson concludes with advanced examples and a summary of key concepts.

What is the first step in solving an exponential equation when the bases are the same?

• Add the exponents

• Set the exponents equal to each other

• Multiply the bases

• Divide the bases

When the bases of an exponential equation cannot be made the same, what is a common method to solve it?

• Subtract the smaller base from the larger base

• Multiply both sides by a factor

• Take the logarithm of both sides

• Add a constant to both sides

Which property of logarithms is used to bring the exponent to the front when solving exponential equations?

• Change of base property

• Product property

• Power property

• Quotient property
