Question

give the right answer​

Answer 1

Answer:

d) none of these

Step-by-step explanation:

1. Cube root of 729 is 9.
2. Now as we can see the base of LHS is 3 so we will bring RHS in terms of 3 which is 3².

That gives us:

3^(3x-3) = 3²

3x-3=2 (as bases are same we can equate the powers)

3x =5

x = 5/3
