To solve this problem, you can use the exponent rule for division which states that when you divide two numbers with the same base, you subtract the exponents.
In this case, 8^? ÷ 8^7 can be written as 8^(?) - 7.
The equation becomes 8^(?) - 7 = 8^13.
Since the bases are the same, the exponents must be equal. Therefore, ? - 7 = 13.
Solving for ?, we add 7 to both sides of the equation: ? = 20.
Therefore, 8^? ÷ 8^7 = 8^20.
8^? ÷ 8^7= 8^13
