Write the expression as a single power using only positive exponents, if possible. assume no denominator equals zero. will give brainliest!

The answer is 1/x^10.

You subtract exponents when you divide, so: x^-6 - x^4. That equals x^-10.

Since the exponent is negative, you must put it in the denominator. Since this fraction has nothing in the numerator, use "1" as a placeholder.

Therefore, the answer is 1/x^10. Hope this helps!
