Answer 2

Answer:

Hey....!!!

The above equation can be written as...

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

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

Now....

According to the rule of indices, if bases are same then the powers can be equated...

Here the bases are same i.e. 3 on both the sides....

So....

x-1 = -3

x = -3 +1

x = -2

Hope this helps....☺️❣️❤️
