log₅(21) = log₅(3) +log₅(7)
Step-by-step explanation:
The relevant relation is ...
log(ab) = log(a) +log(b)
where the logs have any consistent base.
__
Here, we have ,,,
ab = 21 = 3·7.
Then ...
log(21) = log(3) +log(7)
When the logs are to base 5, that becomes ...
I believe it's the third option
I could be wrong, so sorry if it's not correct.
25%
7 apples + 2 peaches = 9
12-9=3
3/12 = 25%
One fourth
C. is correct
Mono means one and 2nd degree is 2 as a exponent.
300 grams
2kg = 2000 grams
15% = 15/100
15/100 × 2000 = 300 grams
