Explicação passo a passo:

$\mathsf{log_b\:a = 4}$

$\mathsf{log_b\:c = 6}$

$\mathsf{log_b\:d = -1}$

$\mathsf{log_b\:\dfrac{a.c}{d} = log_b\:a + log_b\:c - log_b\:d}$

$\mathsf{log_b\:\dfrac{a.c}{d} = 4 + 6 - (-1)}$

$\mathsf{log_b\:\dfrac{a.c}{d} = 10 + 1}$

$\boxed{\boxed{\mathsf{log_b\:\dfrac{a.c}{d} = 11}}}$
