Question

300м2+2га*600а:22см2-100мм3*1дм-200см3​

Answer 1

Объяснение:

1) 300 м²+ 2 га  и 600а:2

 1 га = 10 000 м²

  1 а= 100 м²

300 м²+2*10000=20300 м²

600*100= 60 000 м²

600 00:2=30 000 м²

20 300 м²<  30 000 м², значит

300 м²+2 га < 600 а:2

2) Правильная запись

2 см³-100 мм³ и 1 дм³-200 см³

1 дм³ = 1000 см³

1 мм³=0,001 см³

2 см³- 100*0,001=2 см ³ -0,1 см ³=1,9 см³

1*1000 -200=1000-200 =800 см³

1,9 см³ < 800 см³, значит

2 см³-100 мм³ <  1 дм³-200 см³

Answer 2

To solve the given expression, let's break it down step by step:

1. Convert the units to a common metric system. In this case, we'll convert everything to square centimeters (cm²) and cubic centimeters (cm³) for consistency.

300 m² = 30,000,000 cm² (since 1 m² = 10,000 cm²) 2 hectares (ha) = 20,000 m² = 2,000,000,000 cm² (since 1 ha = 10,000 m² = 1,000,000,000 cm²) 600 ares (a) = 60,000 m² = 6,000,000,000 cm² (since 1 a = 100 m² = 10,000 cm²)

2. Perform the calculations:

2,000,000,000 cm² * 6,000,000,000 cm² = 12,000,000,000,000,000,000 cm⁴ (square centimeters squared) 22 cm² - 100 mm³ * 1 dm - 200 cm³

Note: We'll convert the millimeters (mm) and decimeters (dm) to centimeters (cm) to maintain the same unit.

100 mm³ = 100 cm³ (since 1 cm³ = 1 cm³) 1 dm = 10 cm (since 1 dm = 10 cm)

22 cm² - 100 cm³ * 10 cm - 200 cm³ = 22 cm² - 1,000 cm³ - 200 cm³ = 22 cm² - 1,200 cm³

3. Subtract the values:

12,000,000,000,000,000,000 cm⁴ - (22 cm² - 1,200 cm³)
