Answer:

$\frac{5}{32}$

Step-by-step explanation:

given $\frac{3x+1}{y^{2} }$

substitute x = 3 and y = 4 into the expression

= $\frac{3(3)+1}{4(4)^{2} }$

= $\frac{9+1}{4(16)}$ = $\frac{10}{64}$ = $\frac{5}{32}$

log_a\left( \frac{x}{y}\right)\implies log_a(x)-log_a(y)

log_a\left( x^ b \right)\implies b\cdot log_a(x)\\\\

log_3\left( \cfrac{2r^5}{y^8} \right)\implies log_3(2r^5)-log(y^8)
\\\\\\
\boxed{log_3(2)+log_3(r^5)}-log_3(y^8)\implies log_3(2)+5log_3(r)-8log_3(y)$
