Basile [38]

B

Let’s put this into a simple equation

8 apples = 2.96

We can substitute apples for x

She divided by 8

X= 2.96/8

Remember x represents apples so only 1 x represents 1 apple

So that means the answer is B.

... log(ab) = log(a) +log(b)

_____

The second term 2log(y) can be rewritten as log(y^2). These two rewrites make use of the first rule above.

Now, you have the sum ...

... log(x^7) +log(y^2)

The second rule tells you this can be rewritten as ...

... log(x^7·y^2) . . . . . seems to match the intent of the 3rd selection
