Hello, Shayleigh,
Is the question written correctly? I see "log of 67776 = 5." That doesn't make sense to me because 67776 doesn't equal 5. It equals a humongous (metric term) number that won't fit on my Excel spreadsheet, even with scientific notation.
If the number was supposed to be 67, the result is 279936, so that isn't correct, either.
I do note that:
65 = 7776
So that would produce the following log relationship.
log6(7776)= 5
This tells us the the base, 6, when raised to the power of 5 will result in 7776. I wonder if your question can be answered with this perspective on the question.
