Which expression is equivalent to x^−4 ?

Answer: [tex]\frac{1}{x^{4} }[/tex]Step-by-step explanation:In the expression given, the x has a negative exponent.A negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side changing the sign of the exponent.Then:[tex]x^{-4} =\frac{1}{x^{4} }[/tex]
