Oblicz:
a) 43, 33, 203 b) 23 + 33, 15 + 52, 62 + 84 c) 102 – 92, 76 – 42, 200 – 82
Odpowiedż:
a)
43 = 4 x 4 x 4 = 16 x 4 = 64
33 = 3 x 3 x 3 = 9 x 3 = 27
203 = 20 x 20 x 20 = 400 x 20 = 8000
b)
22 + 33 = 2 x 2 x 2 + 3 x 3 x 3 = 4 x 2 + 9 x 3 = 8 + 27 = 35
15 + 52 = 15 + 5 x 5 = 15 + 25 = 40
62 + 84 = 6 x 6 + 84 = 36 + 84 = 120
c)
102 – 92 = 10 x 10 – 9 x 9 = 100 – 81 = 19
76 – 42 = 76 – 4 x 4 = 76 – 16 = 60
200 – 82 = 200 – 8 x 8 = 200 – 64 = 136
