Question

100см-3см * 70см, 50кг+50кг* 9ц, 1дм2см *2дм, 14л+10л* 5л​

Answer 1

Ответ:

100см-3см * 70см = 6790 см

50кг+50кг* 9ц = 90000 кг

1дм2см *2дм = 240 см

14л+10л* 5л​ = 120 л

Answer 2

To calculate the given expressions, let's perform the necessary calculations step by step:

1. 100 см³ - 3 см * 70 см: First, multiply 3 cm by 70 cm: 3 cm * 70 cm = 210 cm² Then, subtract 210 cm² from 100 cm³: 100 cm³ - 210 cm² = -110 cm³

   Therefore, the result is -110 cm³.

2. 50 кг + 50 кг * 9 ц: First, multiply 50 kg by 9 ц (centners): 50 kg * 9 ц = 450 ц Then, add 450 ц to 50 kg: 50 kg + 450 ц = 50 kg + 450 ц = 50 kg + 45000 kg

   Since the units are different (kg and ц), we cannot directly add them together.

3. 1 дм² * 2 дм: Multiply 1 dm² by 2 dm: 1 dm² * 2 dm = 2 dm³

   Therefore, the result is 2 dm³.

4. 14 л + 10 л * 5 л: Multiply 10 л by 5 л: 10 л * 5 л = 50 л Then, add 50 л to 14 л: 14 л + 50 л = 64 л

   Therefore, the result is 64 л.

To summarize:

• 100 см³ - 3 см * 70 см = -110 cm³
• 50 кг + 50 кг * 9 ц = 50 kg + 45000 kg (units are different, cannot be directly added)
• 1 дм² * 2 дм = 2 dm³
• 14 л + 10 л * 5 л = 64 л
