Answer:

A

Step-by-step explanation:

t to know what i8 is...

Since 8 is an even number, we can factor a 2 out of the exponent of your problem, like this:

i8=(i2)4.

But, i2=-1, so your problem becomes:

-14.

This means, multiply -1 by itself 4 times, to get 1

(Remember, -1 raised to an even power is always 1, so -14=1)

The final answer is: 1
