Full solution

Q. Write the expression as a whole number with a negative exponent. Do not evaluate the expression.\newline18978\frac{1}{89^{78}}
  1. Identify base and exponent: Identify the base and the exponent in the given expression 18978\frac{1}{89^{78}}. In 18978\frac{1}{89^{78}}, 8989 is the base raised to the exponent 7878, and the entire expression is in the denominator. Base: 8989 Exponent: 7878
  2. Apply negative exponent rule: Apply the negative exponent rule to rewrite the expression with a negative exponent.\newlineNegative exponent rule: am=1ama^{-m} = \frac{1}{a^m}\newlineSo, to write 18978\frac{1}{89^{78}} as a whole number with a negative exponent, we can use the rule to get 897889^{-78}.
