Simplify:
log, (3x+4) – 7 log, r° +6log, x

In this case, we have the following expression:

Remember that any number whose exponent is 0 equals 1, so:

Then, we can write our expression as:

We know that:

So our expression becomes:

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.
