Answer:
The value of given expression is 1.
Step-by-step explanation:
The given expression is

If a is a real number, then
.
![[\because a^0=1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E0%3D1%5D)
Using exponent property we get,
![[\because a^{-n}=\frac{1}{a^n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E%7B-n%7D%3D%5Cfrac%7B1%7D%7Ba%5En%7D%5D)


Therefore the value of given expression is 1.
