6 0
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)

Virty [35]

Answer:

Can someone help me understand Inverses for algerbra???
Anna007 [38]

Answer:

An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing. We can write this in terms of the composition of f and g as g(f(x))=x.

Step-by-step explanation:

The inverse function returns the original value for which a function gave the output. ... A function that consists of its inverse fetches the original value.

Example : f(x) = 2x + 5 = y. Then, g(y) = (y-5)/2 = x is the inverse of f(x).
