Determine the Value of an Expression Involving Exponents

Let $$a$$ be a positive integer such that $$a^{2} = 64$$. If you divide $$a^{4}$$ by $$a^{2}$$, what is the value of the expression?

To begin solving, first find $$a$$ from the equation $$a^{2} = 64$$. Then utilize the properties of exponents to simplify the division.
