Question

find the logarithm using the change of base formula. log 4^15

Answer 1

\(\bf \textit{change of base formula}= log_ab=\cfrac{log_cb}{log_ca}\qquad thus\\ \quad \\
log_4(15)\implies \cfrac{log_{10}15}{log_{10}4}\)

Answer 2

well is you current question

\[\log_{10}(4^{15})\]

if not, what is the base...?

Answer 3

hmm btw I'm assuming is \(\large log_4(15)\)

Answer 4

lol... now that is a good question

Answer 5
