=

$\frac{1}{3 { }^{2} }$

, 3

, 27

Answer 2

Answer :

For x = (-2)

$:\implies\sf\:3^x$

$:\implies\sf\:3^{-2}$

$:\implies\sf\:\dfrac{1}{3^2}\:\longrightarrow\:m^{-n}=\dfrac{1}{m^n}$

$:\implies\boxed{\bf{\dfrac{1}{9}}}$

For x = 1

$:\implies\sf\:3^x$

$:\implies\sf\:3^1$

$:\implies\boxed{\bf{3}}$

For x = 3

$:\implies\sf\:3^x$

$:\implies\sf\:3^3$

$:\implies\boxed{\bf{27}}$

Hence, Option-B is correct.
