Question

solve for the variable: log4(5)+log4(x)=log4(20)

Answer 1

use the first law of logs: log a + log b = log ab

Answer 2

\[\log_{4} 5+\log_{4} x=\log_{\log_{4} } 20\]

Answer 3

so would the answer be 4

Answer 4

yes

Answer 5

details:
\[\log_{4} 5+\log_{4} x=\log_{4} 20\]
\[\log_{4} 5x=\log_{4} 20\]
\[5x=4^{\log_{4}20 }\]
\[5x=20\]
\[x=4\]
