4км35м:5-(5км72м-4км23м)

Let's solve the expression step by step.

1. First, convert all distances to the same unit. We'll use meters (m) for simplicity.

• \( 4 \text{ km} \) = \( 4000 \text{ m} \)
• \( 35 \text{ m} = 35 \text{ m} \)

So, \( 4 \text{ km} 35 \text{ m} = 4000 \text{ m} + 35 \text{ m} = 4035 \text{ m} \).

• \( 5 \text{ km} \) = \( 5000 \text{ m} \)
• \( 72 \text{ m} = 72 \text{ m} \)

So, \( 5 \text{ km} 72 \text{ m} = 5000 \text{ m} + 72 \text{ m} = 5072 \text{ m} \).

• \( 4 \text{ km} \) = \( 4000 \text{ m} \)
• \( 23 \text{ m} = 23 \text{ m} \)

So, \( 4 \text{ km} 23 \text{ m} = 4000 \text{ m} + 23 \text{ m} = 4023 \text{ m} \).

2. Now, substitute these values back into the expression:

\[ 4035 \text{ m} : 5 - (5072 \text{ m} - 4023 \text{ m}) \]

3. Calculate \( 5072 \text{ m} - 4023 \text{ m} \): \[ 5072 - 4023 = 1049 \text{ m} \]

4. Now, substitute back into the expression: \[ 4035 \text{ m} : 5 - 1049 \text{ m} \]

5. Calculate \( 4035 \text{ m} : 5 \): \[ 4035 \div 5 = 807 \text{ m} \]

6. Finally, calculate: \[ 807 \text{ m} - 1049 \text{ m} = -242 \text{ m} \]

So, the final result is: \[ -242 \text{ m} \]
