Q. Write the expression as a fraction with a positive exponent.k31
Understand the problem: Understand the problem.We need to convert the expression with a negative exponent into a fraction with a positive exponent.
Apply the negative exponent rule: Apply the negative exponent rule.The negative exponent rule states that a−n=an1 for any nonzero number a and any integer n. Therefore, k−3 can be written as k31.
Check the result: Check the result.We have written k−3 as k31, which is a fraction with a positive exponent. There are no calculations to check for errors in this step, as it is a direct application of the exponent rule.
