If you know that log5 (2) - log5 (12) = 0, which of the following is false?
garri49 [273]

Answer:

B

Step-by-step explanation:

A is correct because log_5(12) was added on both sides, which is supported by the Additive Property of Equality

C is correct because the Quotient Property of Logarithms states that log_bM-log_bN=log_b(\frac{M}{N} )

   so log_5(x)-log_5(12)=log_5(\frac{x}{12} ) is correct

D is correct because using the fact that log_5x=log_512 it is easy to figure out that x=12

For B, there is no property supporting that statement.
