3^(x−1) = 27
I need the answer please and thanks

x=2

Step-by-step explanation:

For the given equation

To find the value of x which is in power of base 3, make the base of R.H.S also 3

Making 27 in the power of three will be written as:   27=

So,                    

Now, we have same base on both the sides, so we can equate their powers of R.H.S and L.H.S.

So, for the equation, the value of x is 2
