    Answer:

      f  2^4 + 2^3 ⋅ 3^2

    Step-by-step explanation:

    16 +2·36 = 16 +2·4·9 = 16 +8·9

      = 2^4 + 2^3 · 3^2 . . . . . matches choice F

    _____

    Since you’re familiar with your multiplication tables, you know …

      4 = 2·2

      8 = 2·4 = 2·2·2 = 2^3

      16 = 2·8 = 2·2·2·2 = 2^4

      9 = 3·3 = 3^2

      36 = 4·9

    The exponent signifies repeated multiplication.
