Solving Logarithmic Equations Challenge

What must be true for two logarithms on either side of an equation to be considered equal?

• They must have different bases.

• Their exponents must be equal.

• Their bases must be the same and their arguments equal.

• They must both be greater than one.

What is the first step in solving an equation that contains a single logarithm?

• Isolate the logarithm on one side of the equation.

• Multiply both sides by the base of the logarithm.

• Add the logarithm to both sides of the equation.

• Convert the logarithm to an exponential form immediately.

What does exponentiating both sides of an equation involving a logarithm accomplish?

• It converts all terms into their exponential counterparts.

• It eliminates the logarithm by using its inverse property.

• It simplifies the logarithm into a linear equation.

• It balances the equation by making both sides equal.
