Tolong jawab ya plis besok pengen dikumpulinya plis jawab bin ini ya tapi pake cara nya oke​

Penjelasan dengan langkah-langkah:

10.

40 = 2³ × 5

30 = 2 × 3 × 5

kpk = 2³ × 3 × 5 = 120 menit = 2 jam

maka

08.36 + 2 jam = 10.36

11.

60 = 2² × 3 × 5

80 = 2^4 × 5

120 = 2³ × 3 × 5

fpb = 2² × 5 = 4×5 = 20

jawabannya 20

12.

(45-25)² – 12² = n

(20)² – 12² = n

400 – 144 = n

256 = n

13.

³√46.656 = 36

karena 36×36×36 = 46.656

14.

V = s³

54872 = s³

³√54872 = s

38 dm = s

15.

2hm + 8 dam + 4m

= 200m + 80m + 4m

= 284 m

3hm + 5dam + 7m

= 300m + 5m + 7m

= 357m

650- 284-357 = 41 m

maaf klo salah
