Q. Write the expression as a whole number with a negative exponent. Do not evaluate the expression.391
Identify Base and Exponent: Identify the base and the exponent in the given expression 391. The base is 3, and the exponent is 9. The expression is the reciprocal of 3 raised to the power of 9.
Apply Negative Exponent Rule: Apply the negative exponent rule to rewrite the expression.The negative exponent rule states that a−m=am1. Therefore, we can write 391 as 3−9.
Check Expression Format: Check if the expression is now written as a whole number with a negative exponent.The expression 3−9 is indeed a whole number (3) with a negative exponent (−9), which satisfies the requirement.
