Q. Write the expression as a fraction with a positive exponent. Do not evaluate the expression. 761
Understand negative exponent rule: Understand the negative exponent rule.The negative exponent rule states that a−m=am1, where a is the base and m is the positive exponent.In this case, a is 7 and m is 6.
Apply negative exponent rule: Apply the negative exponent rule to the given expression.Using the rule from Step 1, we can rewrite 7−6 as 1/76.
Check for errors: Check for any mathematical errors.There are no calculations to perform since we are not evaluating the expression, but we can check that we applied the negative exponent rule correctly. The base 7 remains the same, and the exponent −6 becomes positive in the denominator, which is correct.
