Step-by-step explanation:
Hi there,
To get started, recall the logarithm rules. For this question, we can use the log rule specifically when subtracting two log functions that have the same base:
In this prompt, our base is 4, so b in the above formula. Using this formula, we can find the missing <u><em>argument</em></u> (the number inside of the log, what we are asked to solve for):
hence the missing argument is 9/11
At this point, there is no easier say to simplify, unless you wish to approximate 9/11 as 0.818. If you wish to solve for the exponent, you will have to use common log or natural log to do so.
