(b) 23 ______ 32


(c) 74 ______54


(d) 10,000 ______ 105


(e) 63 _____44

(a) We know that 32 = 3 × 3


= 9


So 9 < 15


Therefore the answer for the fill in the blanks = <


(b) We know that 32 = 3 × 3


= 9


We also know that 23 = 2 × 2 × 2


= 8


So 8 < 9


Therefore the answer for the fill in the blanks = <


(c) We know that 74 = 7 × 7 × 7 × 7


= 49 × 49


= 2401


We also know that 54 = 5 × 5 × 5 × 5


= 25 × 25


= 625


So 2401 > 625
