3(2m - 9 + 6m) = 3m + 29 - 7m
6m - 27 + 18m = 3m + 29 - 7m
24m - 27 = - 4m+ 29
24m + 4m = 29 + 27
28m = 56
m = 56/28
m = 2

Answer:

a) $\log 52$

b) $\log_57$

Step-by-step explanation:

Use logarithm properties:

$\log_ab+\log_ac=\log_a(b\cdot c)\\ \\\log_ab-\log_ac=\log_a\dfrac{b}{c}$

Then

a) $\log 13+\log 4=\log 13\cdot 4=\log 52$

b) $\log_514-\log _52=\log _5\dfrac{14}{2}=\log _57$
