Rewrite the following expression as a single logarithm. Which letter is the correct answer?

Pepsi [2]

Answer: OPTION B

Step-by-step explanation:

You need to remember the logarithms properties:

$log(a)+log(b)=log(ab)\\\\log(a)-log(b)=log(\frac{a}{b})\\\\log(a)^b=blog(a)$

Then, you can rewrite the expression as a single logarithm:

$log(x+3)^2+log(x-7)^3-log(x-2)^5-log(x^2)\\\\log((x+3)^2(x-7)^3)-log(\frac{(x-2)}{(x^2)})\\\\log(\frac{(x+3)^2(x-7)^3}{x^2(x-2)^5})$

This matches with the option B.
