Answer 1

Answer:

Option 2nd is correct

$9^x-3 =9^3$

Step-by-step explanation:

Given the equation:

$9^x-3 = 729$

We can write 729 as

$729 = 9 \cdot 9 \cdot 9 = 9^3$

then;

$9^x-3 =9^3$

Therefore, the equation which is equivalent to $9^x-3 = 729$ is, $9^x-3 =9^3$

Answer 2

The answer is 9^x-3=9^3
