Solving Exponential Equations: Key Concepts and Techniques

What is the main challenge in solving exponential equations?

• Finding the variable in the exponent

• Finding the coefficient

• Finding the exponent

• Finding the base

What is the first step in solving exponential equations?

• Take the square root of both sides

• Express each side with the same base

• Multiply both sides by the same number

• Divide both sides by the same number

If B^X = B^Y, what can we conclude?

• X and Y are unrelated

• X must be less than Y

• X must be greater than Y

• X must be equal to Y

In the equation 27^X = 3^(X+8), what is the first step to solve it?

• Take the logarithm of both sides

• Divide both sides by 27

• Convert 27 to a power of 3

• Multiply both sides by 3
