00:01
Right there.
00:01
In this question, we are looking for which expression is equal to logarithm base b3.
00:07
So let's do the first one.
00:10
And there is a subtraction between them.
00:12
So if you have a subtraction, we have, we can just write this expression as a logarithm base b and 27 over 9.
00:21
So 27 over 9, which is 3.
00:23
So that means this is logarithm base b3.
00:25
So that is equal to logarithm base b3.
00:28
That is true.
00:30
What about the next one? and there is an addition here.
00:34
So for the additional two logaritimes, we just multiply if the base is the same.
00:39
So the bases are the same.
00:42
So we can just write this expression as 1 over 10 times 30.
00:47
So we can just write as logarithm base 3, which is also equal to logarithm base 3...
