Question

Which expressions are equivalent to the one below? Check all that apply.

Answer 1

Answer:

A & B

Step-by-step explanation:

Answer 2

Answer:

Recall from Logarithm law Log a - Log b = Log (a/b)

so, Log 2 - Log 4 = Log ( 2/4)

                            = Log ( 1/2).

Also from the law

Log (a/b) = Log a - Log b

i.e Log (1/2) = Log 1 - Log 2

Recall: Log 1 = 0

which implies : Log 1 - Log 2 = 0 - Log 2

                                               = - Log 2
