Arrange the following symbols in the increasing order of lengths they represent
dm cm m km dam Mm mm `mu m`

Explanation

To arrange the symbols in the increasing order of lengths they represent, we need to convert each unit to meters and compare their values. Here’s the step-by-step solution:

### Step 1: Understand the units and their conversions
1. **Micrometer (µm)**: \(1 \, \mu m = 10^{-6} \, m\)
2. **Millimeter (mm)**: \(1 \, mm = 10^{-3} \, m\)
3. **Centimeter (cm)**: \(1 \, cm = 10^{-2} \, m\)
4. **Decimeter (dm)**: \(1 \, dm = 10^{-1} \, m\)
5. **Meter (m)**: \(1 \, m = 1 \, m\)
