Tolong yahkkkkkkkk!!!

1) 15.245 + 3.571 - 7.902
= 18.816 - 7.902
= 10.914 (C)

2) n = 26.459 × 24 ÷ 8
n = 26.459 × 3
n = 79.377 (B)

3) 2.385 - 96 × 13 + (-56) ÷ 4
= 2.385 - 1.248 + (- 14)
= 1.137 - 14
= 1.123 (B)

4) 24 - 28 + 12
= (-4) + 12
= 8°C (C)

5) 24 = 2³ × 3
36 = 2² × 3²
48 = 2⁴ × 3
kpk = 2⁴ × 3² (A)

6) 6 = 2 × 3
12 = 2² × 3
16 = 2⁴
kpk = 2⁴ × 3 = 48
jadi mereka berlatih bersama lagi setiap 48 hari lagi (D)

7) 17² - 13²
= (17 + 13) × (17 - 13)
= (17 - 13) × (17 + 13)
= 4 × 30
= 120
berarti yg bukan hasil dari 17² - 13² adalah
34 (D)
