Q. Write the expression as a whole number with a negative exponent. Do not evaluate the expression.72921
Identify Base and Exponent: Identify the base and the exponent in the given expression 72921. In 72921, 72 is the base raised to the exponent 92, and the entire expression is in the denominator, indicating a negative exponent for the reciprocal. Base: 72 Exponent: 92
Apply Negative Exponent Rule: Apply the negative exponent rule to rewrite the expression.Negative exponent rule: a−m=am1So, to write 72921 as a whole number with a negative exponent, we apply the rule in reverse:72921=72−92
