F(0) = replace every x with 0

=9.0710678119
=9.07
I think the answer is c because it is a even number and the answer can also be a but i think it is c
Answer:
log x^13.
Step-by-step explanation:
Using the laws of logarithms
a log b = log b^a and log a + log b = log ab:
3 log x^2 + 7 log x
= log (x^2)^3 + log x^7
= log x^6 + log x^7
= log (x^6*x^7)
= log x^13.
Minus 6 both sides
4>x/3
times3 both sides
12>x
