Write the expression as a single logarithm Log7X+log7Y-log7Z
1 answer:
For this, simply use the rules of logs:
- Adding logs of the same base (which is 7 here) is the same as multiplying
-Subtracting logs of the same base is dividing
So the single log would be:
log₇(x*y/z) which is the same as
log₇(xy/z)
