Full solution

Q. Write the expression as a whole number with a negative exponent. Do not evaluate the expression.\newline19087\frac{1}{90^{87}}
  1. Understand Expression: Understand the given expression.\newlineThe given expression is 19087\frac{1}{90^{87}}. We need to rewrite this expression as a whole number with a negative exponent without evaluating it.
  2. Apply Negative Exponent Rule: Apply the negative exponent rule. The negative exponent rule states that am=1ama^{-m} = \frac{1}{a^m}. To apply this rule to the given expression, we rewrite 19087\frac{1}{90^{87}} as 908790^{-87}.
  3. Check Final Expression: Check the final expression.\newlineThe final expression is 908790^{-87}. This is a whole number (9090) with a negative exponent (87-87), which is what the question prompt asked for.
