Dahlia is simplifying (3 t) Superscript 4 using these steps: (3 t) Superscript 4 = 3 t times 3 t times 3 t times 3 t = 3 times 3 times 3 times 3 times t times t times t times t Although Dahlia is correct so far, which step could she have used instead to simplify the expression (3 t) Superscript 4? (3 t) Superscript 4 = 3 t Superscript 4 3 Superscript 4 Baseline t = 81 t 4 (3 t) = 12 t 3 Superscript 4 Baseline t Superscript 4 Baseline = 81 t Superscript 4
