Question

Use change-of-base formula to find three significant digits...

Answer 1

\[\log_{2} 6+ \log_{3} 5\]

Answer 2

(log 6 / log 2) + (log 5 / log 3)

finding l.c.m
(log 3 . log 6 + log 2 . log 5) / (log 2 . log 3)
But log 3 = 0.4771
log 2 = 0.3010
log 5 = 0.6990
log 6 = 0.7782

=> (0.4771 . 0.7782 + 0.3010 . 0.6990) / (0.3010 . 0.4771)
\[\approx4.0505\]
