Answer 1

1) 541см > 5м 4дм (т.к 1м=10дм=100см.) 541см>540см
2) 73кг>739г (т.к 1кг=1000г.) 73000г>739г
3) 5ч 45мин < 500мин (т.к 1ч=60мин) 5*60+45=345мин.   345мин<500мин.

Answer 2

To calculate the given expressions, let's convert the measurements to a consistent unit before performing the multiplication.

1. 541 cm * 5 m 4 dm: First, convert 5 m to cm: 5 m * 100 cm/m = 500 cm. Then, convert 4 dm to cm: 4 dm * 10 cm/dm = 40 cm. Now we can multiply: 541 cm * (500 cm + 40 cm). Simplifying, we get: 541 cm * 540 cm = 292,740 cm².

2. 73 kg * 739 g: Convert 73 kg to grams: 73 kg * 1000 g/kg = 73,000 g. Now we can multiply: 73,000 g * 739 g = 53,947,000 g².

3. 5 hours 45 minutes * 500 minutes: Convert 5 hours to minutes: 5 hours * 60 minutes/hour = 300 minutes. Now we can multiply: (300 minutes + 45 minutes) * 500 minutes. Simplifying, we get: 345 minutes * 500 minutes = 172,500 minutes².

So, the results are:

1. 541 cm * 5 m 4 dm = 292,740 cm².
2. 73 kg * 739 g = 53,947,000 g².
3. 5 hours 45 minutes * 500 minutes = 172,500 minutes².
