Question

30м10см-19дм6см+8м4дм

Answer 1

3010 см - 196 см + 840 см = 3724 см или 37 м 2 дм 4 см

Answer 2

To solve the arithmetic expression, let's convert all the measurements to a consistent unit, such as centimeters.

30 м (m) is equal to 3000 см (cm) because 1 meter is equal to 100 centimeters. 10 см (cm) remains as it is. 19 дм (dm) is equal to 190 см (cm) because 1 decimeter is equal to 10 centimeters. 6 см (cm) remains as it is. 8 м (m) is equal to 800 см (cm). 4 дм (dm) is equal to 40 см (cm).

Now, let's perform the calculation:

(3000 см + 10 см) - (190 см + 6 см) + (800 см + 40 см)

= 3010 см - 196 см + 840 см

= 3654 см

Therefore, the result of the arithmetic expression 30м10см - 19дм6см + 8м4дм is 3654 см (centimeters).
