I rewrite yoyr expression as below: $\Large \frac{{{3^{ - 6}}}}{{{3^x}}} = {3^4}$ Now I apply the rule of division of power with the same basis, so I get this condition: $\Large - 6 - x = 4$ please solve for x

hint: If I add 6 to both sides, I get: $\Large - 6 - x + 6 = 4 + 6$

11. Testing123guest

-2?

12. Michele_Laino

after a simplification I get this: $\Large - x = 10$
