Penjelasan dengan langkah-langkah:

1

(93 - 58)³ + ³√17.576

93 - 58 = 35³ = 42.875

³√17.576 = 26

42.875 + 26 = 42.901

2.

skala = 1 : 150

kamar adik = 3 × 2

3 × 150 = 450

2 × 150 = 300

luas = 450 × 300 = 135.000 cm³ = 13,5 m³

3.

jp = 8cm

js = 180km = 18.000.000cm

skala = 18.000.000 ÷ 8 = 2.250.000

jadi skala peta = 1 : 2.250.000

4.

2,4 ton + 18 kuintal - 2.575 kg = .... kg

2,4 × 1000 = 2400 kg

18 × 100 = 1800 kg

2400 + 1800 - 2575 = 4200 - 2575 = 1.625 kg

5.

200 m + 50dm - 21.000 cm = .... m

50dm ÷ 10 = 5m

21.000 ÷ 100 = 210m

200 + 5 - 210 = -5m
