Answer 1

Explicație pas cu pas:

64:(2×4)=64:8=8 => 2×4×8 = 64

42:(3×2)=42:6=7 => 3×7×2 = 42

36:(4×1)=36:4=9 => 4×1×9 = 36

28:(2×2)=28:4=7 => 2×2×7 = 28

27:(3×3)=27:9=3 => 3×3×3 = 27

54:(2×3)=54:6=9 => 2×3×9 = 54

56:(4×2)=56:8=7 => 4×2×7 = 56

72:(3×3)=72:9=8 => 3×3×8 = 72

64:(4×8)=64:32=2 => 2×4×8 = 64
