Above is an example of the long way to simplify the problem (in black). The short way is in red.
Above: remember that 2 - 8 = -6. But in terms of writing with exponents, bases with negative exponents are written in the denominator as positive exponents. Try the above the long way and you will see.
Above, remember the rule: a number over itself, except for zero, is one.
Above is written the long way to show the final answer. Remember that when dividing, your keep the base and subtract the exponents.
