Solving Exponential Equations in Algebra 2

Why is it important to convert exponential equations to logarithmic form?

• To simplify the equation

• To use a calculator

• To solve for the exponent when it's not a whole number

• To change the base of the equation

What is the first step in solving an exponential equation?

• Convert to logarithmic form

• Get the base raised to a power by itself

• Subtract from both sides

• Use the change of base formula

What does the change of base formula allow you to do?

• Simplify the logarithm

• Change the base of the logarithm

• Use any base in calculations

• Solve for the exponent directly

How do you use the change of base formula with a calculator?

• Log of the base divided by log of the number

• Log of the number divided by log of the base

• Natural log of the base divided by natural log of the number

• Natural log of the number divided by natural log of the base

What is the result of log(20) / log(8) using the change of base formula?

• 0.95

• 2.00

• 1.44

• 1.25

What should you do if you encounter a negative number in a logarithm?

• Use the natural log instead

• Change the base

• There is no solution

• Subtract from both sides

How do you handle an equation with e to the negative x power?

• Subtract from both sides

• Convert to natural log

• Divide by the base

• Use the change of base formula

What is the value of x if 4^(x-6) = 10?

• 8.66

• 7.66

• 6.66

• 9.66

What is the value of x if 2^x = 4?

• 2

• 4

• 1

• 3

Why is it important to round to two decimal places?

• To make the answer look neat

• To avoid significant errors

• To simplify calculations

• To match the calculator's precision
