Answer:
The correct answer is option c
7
Step-by-step explanation:
<u>Points to remember</u>
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)
<u>To find the correct option</u>
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
6n + 6m - m - 3n = 6n - 3n + 6m - m = 3n + 5n
2m + 2m + 2n + n = 4m + 3n
