Q. Write the following expression without negative exponents and without parentheses.\newline−2x−3 -2 x^{-3} \newlineAnswer:
  1. Apply Rule for Negative Exponent: To remove the negative exponent, recall that a−n=1ana^{-n} = \frac{1}{a^n}. Apply this rule to the expression −2x−3-2x^{-3}.\newlineCalculation: −2x−3=−2×(1x3)-2x^{-3} = -2 \times \left(\frac{1}{x^3}\right)
  2. Combine Constants and Terms: Now, simplify the expression by combining the constants and the xx term.\newlineCalculation: −2×(1/x3)=−2/x3-2 \times (1/x^3) = -2/x^3
