What is the one-to-one property in logarithmic equations?

• If log base B of M equals log base B of N, then M equals B.

• If log base B of M equals log base B of N, then B equals N.

• If log base B of M equals log base B of N, then B equals M.

• If log base B of M equals log base B of N, then M equals N.

What should you do first when solving a logarithmic equation where log equals log?

• Check for extraneous solutions.

• Condense each logarithm.

• Isolate the variable.

• Rewrite the equation in exponential form.

Why can't a logarithm have a negative argument?

• Because logarithms can only have positive arguments.

• Because it would result in a complex number.

• Because it would result in an undefined value.

• Because it would result in a zero value.
