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

log (10^7)

a 1

b 7

c 7•log 10

d 7•10

B and C

Step-by-step explanation:

Evaluating the given logarithm gives you 7, so we know B is equivalent.

Additionally, the Power Property allows you to pull out the 7 from the exponent and put it in front of the logarithm.

If we were to do this, we would get 7 • Log 10.

So, we know C is equivalent as well.
