The question in the image is asking to convert each numeral into a decimal numeral, meaning the standard base-10 numeric form.

### Analyzing the Symbols

1. **Part (a):** The symbols are in the Mayan numeral system.
   - Mayan numerals consist of dots (worth 1), bars (worth 5), and shells (representing 0).
   - Starting from the bottom, each row represents a power of 20:
      - The bottom row is \(20^0\) (units place).
      - The second row is \(20^1\) (twenties place), and so on.

2. **For Part (a):**
   - From bottom to top:
      - The lowest level has 3 bars and 4 dots. Since each bar represents 5 and each dot represents 1:
        \[
        3 \times 5 + 4 \times 1 = 15 + 4 = 19
        \]
      - The level above it has a single dot, which represents \(1 \times 20 = 20\).
   - Total = \(20 + 19 = 39\).

   So, **(a) = 39**.

3. **For Part (b):**
   - This configuration shows a single symbol for each power of 20.
   - From bottom to top:
      - The bottom row has 2 bars, which represent \(2 \times 5 = 10\).
      - The row above has a single shell symbol, which represents 0.
   - Total = \(10\).

   So, **(b) = 10**.

### Tip
In Mayan numerals, each level up represents a power of 20, which makes it distinct from other numeral systems like Roman numerals, which don’t use place values.

Write each numeral as a decimal numeral. By decimal numeral, we mean the system we use in everyday arithmetic.
