`log ((7c^3)/d^8)`

`` First we will use the quotient properties:

`log (a/b) = log a - log b `

`=gt log (7c^3) - log d^8`

`` Now we will use the product property:

`==gt log ab = log a + log b `

`==gt log 7 + log c^3 - log d^8`

Now we will use the power property:

`==gt log a^b= blog a `

`==gt log 7 + 3log c - 8log d`
