Fatima evaluated the expression StartFraction 4 m Superscript negative 3 Baseline n Superscript negative 2 Baseline Over m Superscript negative 1 Baseline n EndFraction, when m = negative 2 and n = 4. Her work is shown below. StartFraction 4 m Superscript negative 3 Baseline n Superscript negative 2 Baseline Over m Superscript negative 1 Baseline n EndFraction = 4 m Superscript negative 2 Baseline n Superscript negative 3 Baseline = 4 (negative 2) Superscript negative 2 Baseline (4) Superscript negative 3 Baseline = StartFraction 1 Over 64 EndFraction times StartFraction 1 Over 64 EndFraction = StartFraction 1 Over 4,096 EndFraction What was Fatima’s error? She subtracted the exponents incorrectly when simplifying the expression. She substituted the wrong values for the variables. She applied the exponent Negative 2 to 4 (negative 2) instead of applying the exponent to just Negative 2. She found an incorrect value for (Negative 8) Superscript negative 2 since the value should be negative.
