в) 15³ - 3³ · 5;
1) 15³ = 15 × 15 × 15 = 3375
2) 3³ = 3 × 3 × 3 = 27
3) 27 × 5 = 135
4) 3375 - 135 = 3240
3375 - 135 ------ 3240
г) (10³ – 6³) : (2⁴ · 7²).
1) 10³ = 10 × 10 × 10 = 1000
2) 6³ = 6 × 6 × 6 = 216
3) 1000 – 216 = 784
1000 - 216 ------ 784
4) 2⁴ = 2 × 2 × 2 × 2 = 16
5) 7² = 7 × 7 = 49
6) 16 × 49 = 784
16 ×49 ----- 144 64 ----- 784
7) 784 : 784 = 1
