in this question, we're going to make use off to logarithmic rules. The 1st 1 state that if the base and the value or the same, then the whole log becomes one, right? The other rule that we need here is that lock off a base A with the value B to the power off. See, will become. See Look a be right. So take note If this when these two are the same, then the whole lock becomes one. When I have the value to an exponents, the exponents goes, multiply in front and you still have the lock off a B. So for the 1st 1 in log 6 36 we can really want the 36 as six to the power off to six square and now, from the second through, the two can multiply in front and we have left Log off by 66 which we've seen from the first rule is equal to one the whole, off the whole log. So that gives us two. All right. At B, we have the log off nine. 81. So the basis nine and we have 81. So in this case, we can relight the 81 as nine squeak, taking the to to the front, multiplying it with the whole log. Then we see that Locke based 99 is one again from the first room and that also end up to be to Then we have log, see even by 77 to the power off 10. So now the team can multiply in front and we still have by 77 in the lager of them. On that end, up to be one again And the answer East thing 10.
