Q. Write the expression as a fraction with a positive exponent. x41
Understand the problem: Understand the problem.We need to convert the expression with a negative exponent into a fraction with a positive exponent.
Apply negative exponent rule: Apply the negative exponent rule. The negative exponent rule states that a−n=an1 for any nonzero number a and positive integer n. We will apply this rule to x−4.
Rewrite as fraction: Rewrite the expression as a fraction.Using the rule from Step 2, we can write x−4 as x41.
Check the result: Check the result.The expression x41 has a positive exponent, as required. The base x is the same, and the exponent is now positive in the denominator of the fraction.
