Solving Exponential equations

The video tutorial explains how to solve an equation using logarithms. It starts by discussing the limitations of using exponents and introduces the one-to-one properties of logarithms. The instructor then explains how to choose the appropriate base for the logarithms and demonstrates solving the equation using the change of base formula. The tutorial concludes with the final calculation and solution, emphasizing the application of logarithmic properties.

What is the initial problem discussed in the video?

• Determining the base of a logarithm

• Calculating the square root of 15

• Finding the value of X in a quadratic equation

• Solving 7 raised to the power of 9X equals 15

Why can't the one-to-one properties of exponents be used directly in the problem?

• Because the values are irrational

• Because the exponents are too large

• Because the bases are not the same

• Because the equation is not quadratic

What is the significance of choosing the same base for logarithms in the equation?

• It simplifies the equation to just the exponent

• It eliminates the need for division

• It makes the equation more complex

• It changes the base of the exponent

How is the logarithmic expression evaluated in the final section?

• By approximating the value of 15

• By directly calculating log base 7

• Using a graphing calculator

• Using the change of base formula with natural logarithms

What is the approximate value of X as calculated in the video?

• 1.55

• 3.14

• 2.75

• 0.95
