(-5)^11
Since we have the same base for the exponent (-5) in both the numerator and the denominator, we can combine the exponents. As this is a fraction, which means dividing, we subtract the the exponents. (This is just a rule. When dividing exponents with the same base, subtract the powers.) So if we subtract 5 minus -6 we get 11. So we’re left with -5 raised to the 11th power, or (-5)^11
