Answer:

y=(1)/(81)

Explanation:

Given equation:

y=3^x

Substitute x = -4 into the equation:

$\implies y=3^(-4)$

$\textsf{Apply exponent rule} \quad a^(-n)=(1)/(a^n):$

$\implies y=(1)/(3^4)$

Simplify:

$\implies y=(1)/(3*3*3*3)$

$\implies y=(1)/(9*3*3)$

$\implies y=(1)/(27*3)$

$\implies y=(1)/(81)$
