ln(x+2)-7ln(x)+3ln(x+7)

Property 1.
ln(x^n) = nln(x)
For example
ln(105) = 5ln(10) or ln(x^7) = 7ln(x)
Property 2.
ln(x * y) = ln(x) + ln(y)
Property 3.
ln(x/y) = ln(x) - ln(y)

Property 4.
ln(ex) = x

Please be careful because
ln(x + y) is not = ln(x) + ln(y)
nor ln(x - y) is not = ln(x) - ln(y).
