You can put this solution on YOUR website!
Logarithms are exponents. The rules for exponents are the same as those for logarithms.

Your given expression should be shown this way for pure text for purposes of using this algebra.co system.
3*log(c,(x-7))-log(c,y)


With the use of the rendering tags: 3%2Alog%28c%2C%28x-7%29%29-log%28c%2Cy%29

STEPS:

log%28c%2C%28x-7%29%5E3%29-log%28c%2Cy%29

log%28c%2C%28x-7%29%5E3%29%2B%28-log%28c%2Cy%29%29

log%28c%2C%28x-7%29%5E3%29%2B%28log%28c%2C%28y%5E%28-1%29%29%29%29

log%28c%2C%28%28%28x-7%29%5E3%29%2F%28y%29%29%29
