Which statement describes what these four powers have in common? 4 Superscript 0 (negative 2) Superscript 0 (one-third) Superscript 0 9 Superscript 0 All the powers have a value of 0 because the exponent is zero. All the powers have a value of 1 because the exponent is zero. All the powers have a value of –1 because the exponent is zero. All the powers have a fractional value because the exponent is zero.
