Here's your answer

________________________

Given , 3^( x - 1 ) = 1 / 27

To find the value of x

Now ,

3^( x - 1 ) = 1 / 27

3^( x - 1 ) = 1 / 3³

3^( x - 1 ) = 3^( - 3 )

( x - 1 ) = - 3

[ • Bases are same so taking the powers ]

x = - 3 + 1

x = - 2 [ ★ Required answer ]

So , the value of x is - 2
