Answer
$1.792$
Work Step by Step
Using the properties of logarithms, the given expression, $
\log_b 3b
,$ is equivalent to
\begin{array}{l}\require{cancel}
\log_b 3+\log_b b
.\end{array}
Since it is given that $\log_b 3=0.792 $ and that $\log_b b=1,$ the expression above, $
\log_b 3+\log_b b
$, evaluates to
\begin{array}{l}\require{cancel}
0.792+1
\\\\=
1.792
.\end{array}
