Is a negative number with a negative exponents positive?
If the exponent is an even number, then yes, because exponents are basically repeated division and negatives always cancel each other out in division. However if the exponent is an odd number, the number will remain negative, because they can't form even pairs to cancel one another out.

The two negatives cancel out and the number becomes positive.
