Answer:
3
Step-by-step explanation:
Remember that when we are dividing two exponents with the same base (here, it's 13), we can subtract the values of the powers:
So, here, we have 
, so we subtract 7 from 10:
Thus, 3 should go in the box.
You multiply the denominator on one side of the equation by the numerator and vice versa. So for example(S)I'm going to multiply 4 by nine and 3 times n. Then that comes out to 3n=36. After you multiply, you divide from both sides to get the variable by itself. So you would divide both sides by 3 and you're final answer would be n=13. Hope this helped!
