  1. So you have (8^6)/((8^4)*(8^2)). I would start with the denominator. When you are multiplying exponents with the same base, you add the exponents. So the above equation becomes (8^6)/(8^6). This simplifies to 1.

    For the second problem, it's slightly different. You have (4^5)/(4^2). Whenever you are dividing exponents by the same base, you subtract them. So the problem becomes 4^3, which is 64.
