Answer:

log_{b} (5b) = 2.609

Given that:

log_{b} (3) = 1.099

log_{b} (5) = 1.609

Evaluating with that:

\sf log_b (5b) = log_b\left(5\right)+log_b\left(b\right)

            = \sf 1.609 + 1

             = \sf 2.609

Rule Used:

\rm \log _a\left(xy\right)=\log _a\left(x\right)+\log _a\left(y\right)
