Which expression is equivalent to log(10^7), a. 7.10 b. 7.log 10 c. 7 d. 1

The  correct answer is option c

7

Step-by-step explanation:

Points to remember

Log(x^a) = a log x

log 10 = 1    [since the base is 10]

It is given that, correct answer is option c

7

log(10^7)

To find the correct option

By using logarithmic  identities we can write,

log(10^7) = 7 log 10

 = 7 * 1      [ since log 10 = 1]

 = 7

Therefore the  correct answer is option c
