Nadine and calvin are simplifying the expression (startfraction r superscript negative 5 baseline s superscript negative 3 baseline over r superscript 8 baseline s superscript negative 2 baseline endfraction) superscript negative 4. nadine claims the first step to simplify the expression is to raise the numerator and denominator to the power of 4 to get startfraction r superscript negative 20 baseline s superscript negative 12 baseline over r superscript 32 baseline s superscript 8 baseline endfraction. calvin claims the first step to simplify the expression is to apply the quotient of powers to get (r superscript negative 13 baseline s superscript negative 1 baseline) superscript negative 4. who is correct and why?
