Q. Write the expression as a fraction with a positive exponent. Do not evaluate the expression. \newline137\frac{1}{3^7}
  1. Identify base and exponent: Identify the base and the exponent in the expression 3−73^{-7}.\newlineIn 3−73^{-7}, 33 is the base raised to the exponent −7-7.\newlineBase: 33\newlineExponent: −7-7
  2. Apply negative exponent rule: Apply the negative exponent rule to write the expression as a fraction with a positive exponent.\newlineNegative exponent rule: a−m=1ama^{-m} = \frac{1}{a^m}\newlineSo, 3−73^{-7} can be written as 137.\frac{1}{3^7}.
