##### What is solution of (-1)^-n (n is for all integer)...? ____________________________________

##### Explanation
```                      -n
Before solution of (-1)
```

Let us see the solution of -1 base to power 2 and 3.

```We know that
2
(-1)  = 1
And
3
(-1)  = -1
```

therefore -1 to any EVEN power is 1 and -1 to any ODD power is -1. By putting this rule to all integers. We get ...

```                                             _
n                                     |
(-1) = 1      if n is EVEN                |
n                                       >
(-1) = -1     if n is ODD                 |
_|

Similarly

-n      1        1                   _
(-1)   = ------- = ---- = 1  if x is EVEN |
n      1                    |
(-1)                            |
|
-n      -1       1                      >
(-1)   = ------ = ---- = -1  if x is ODD  |
n    -1                     |
(-1)                            |
_|

```

Final answer will be 1 when n is EVEN and -1 when n is ODD.
