Which expression results when the change of base formula is applied to log4 (x + 2)?
You haven't shared the possible answers, so the best I can do (which is very good!) is to assume we want to change from base 4 to base 10 and then apply the change of base formula.
Given log-to-the-base-4-of (x+2), we want log-to-the-base-10 of (x+2). Following the change of base formula,
log-to-the-base-4-of (x+2)
log-to-the-base-10 of (x+2) = ------------------------------------
log-to-the-base-4-of-10
Answer: \(log_4(x+2)=\frac{log (x+2)}{log 4}\)
Step-by-step explanation:
By the log base formula,
\(log_b x = \frac{log_a x}{log_a b}\)
Where a and b are any numbers,
Here the given expression,
\(log_4(x+2)\)
Thus, by the above formula,
We can write,
\(log_4(x+2)=\frac{log_{10} (x+2)}{log_{10} 4 }\)
\(\implies log_4(x+2)=\frac{log(x+2)}{log 4}\)
