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
