D. 18

Answer

To solve the expression `(20div5)div2+(16div8)xx2+(10div5)xx(3div2)`, we will follow the order of operations, often remembered by the acronym BODMAS/BIDMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

### Step-by-Step Solution:

1. **Calculate the divisions:**
- First, we will calculate `20 div 5`.
\[ 20 \div 5 = 4 \]
- Next, calculate `16 div 8`.
\[ 16 \div 8 = 2 \]
- Then, calculate `10 div 5`.
\[ 10 \div 5 = 2 \]
- Finally, calculate `3 div 2`.
\[ 3 \div 2 = 1.5 \]

2. **Substitute the results back into the expression:**
Now we can rewrite the original expression using the results from the divisions:
\[ (4) \div 2 + (2) \times 2 + (2) \times (1.5) \]

3. **Perform the remaining operations:**
- Calculate `4 div 2`.
\[ 4 \div 2 = 2 \]
- Calculate `2 x 2`.
\[ 2 \times 2 = 4 \]
- Calculate `2 x 1.5`.
\[ 2 \times 1.5 = 3 \]

4. **Combine the results:**
Now we add all the results together:
\[ 2 + 4 + 3 = 9 \]

### Final Answer:
The value of the expression is \(9\).
