Answer:
The correct answer is option c
7
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
7
