Question 132129: -a-n an-1 a1(-a)-n
____________ Simplify. N is an even number
a-n
I couldnt do exponents in this format so the problem reads negative a to the negative n, times a to the n minus 1, times a to the 1, times negative a to the negative n, over a to the negative n.

negative a to the negative n, times a to the n minus 1, times a to the 1, times negative a to the negative n, over a to the negative n.
Does it look like this: %28-a%5E%28-n%29%2Aa%5E%28n-1%29%2Aa%5E1%2A%28-a%5E%28-n%29%29%29%2F%28a%5E%28-n%29%29+???

If so, then notice that the factors of a%5E%28-n%29 on the right side of the numerator and the denominator divide out, leaving a factor of -1.

-a%5E%28-n%29%2Aa%5E%28n-1%29%2Aa%5E1%2A%28-1%29+


Next, the negative of a negative is a positive:
a%5E%28-n%29%2Aa%5E%28n-1%29%2Aa%5E1+

What is left is all with base number a, so write down the base number and add exponents:
a%5E%28-n%2Bn-1%2B1%29
a%5E0
