    it would be 8x the x has a negative exponent making it move from the bottom to the top so the exponent will be positive

    When x^-1 is taken to the numerator, the negative sign becomes positive(the sign changes)... so, it becomes 8x^1.... x^1 is nothing but x multiplied once... so it becomes 8x

    since anything to the 0 power is 1 and the y^-4 would move to the top making it positive y^4 and 1 times y^4 is y^4
