Question

3. Evaluate Please help

Answer 1

Explanation:

3^(-2), 3¹, 3³

=

`\frac{1}{3 { }^(2) }`

, 3

, 27

Answer 2

For x = (-2)

`:\implies\sf\:3^x`

`:\implies\sf\:3^(-2)`

`:\implies\sf\:(1)/(3^2)\:\longrightarrow\:m^(-n)=(1)/(m^n)`

`:\implies\boxed{\bf{(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.
