Khan Academy: Solve Exponential Equations Using Logarithms: Base 10 and Base E

Use the resource to teach methods for solving exponential equations. Scholars solve exponential equations using logarithms in the twenty-fifth installment of a 35-part module. Equations of the form ab^(ct) = d and f(x) = g(x) are...

The power to solve exponential equations lies in the resource. Scholars first learn how to solve exponential equations. An activity matching cards with equations, intermediate steps, and solutions strengthens this skill.

Introducing exponential equations means learners need to take all the rules and tricks they learned for exponents and actually apply them. This presentation comes to the rescue by touching on changing bases in exponential...

Sal first solves some equations using the factoring method he has already taught. Next, he introduces the quadratic formula and demonstrates how to plug the numbers from the quadratic equation into the quadratic formula. He then solves...

The teacher demonstrates how to use the addition property of equality, applying it to both sides of the equation to find the solution.

The teacher demonstrates how to use the division property of equality, applying it to both sides of the equation to find the solution.

The teacher demonstrates how to use the multiplication property of equality, applying it to both sides of the equation to find the solution.

The teacher demonstrates how to use the subtraction property of equality , applying it to both sides of the equation to find the solution.

Algebra young scholars use manipulatives to solve linear equations. They use manipulatives, symbolic methods, and substitution to demonstrate each algebraic solution.

Log some practice with logarithms. A PowerPoint presentation provides a tutorial on the change of base formula involving natural logarithms and solving exponential equations with logarithms in the fourth installment of a seven-part...
