Answer:


log_(a) 12

Explanation:

using the properties of logarithms

• nlog x ⇔ log
x^(n)

• log x + log y = log (xy)


(1)/(2)
log_(a) 16 +
(1)/(3)
log_(a) 27

=
log_(a)
16^{(1)/(2) } +
log_(a)
27^{(1)/(3) }

=
log_(a)
√(16) +
log_(a)
\sqrt[3]{27}

=
log_{a 4 +
log_(a) 3

=
log_(a) (4 × 3)

=
log_(a) 12
