Give the number of significant figures
`2.653xx10^(4)`

Answer

To determine the number of significant figures in the number \(2.653 \times 10^4\), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Non-Zero Digits**:
- In the number \(2.653\), the digits are 2, 6, 5, and 3. All of these are non-zero digits.

2. **Count the Non-Zero Digits**:
- Count the non-zero digits identified in the previous step. Here, we have four non-zero digits: 2, 6, 5, and 3.

3. **Consider the Scientific Notation**:
- The number is expressed in scientific notation as \(2.653 \times 10^4\). The exponent (10^4) does not affect the count of significant figures.

4. **Conclusion**:
- Since all the non-zero digits are significant, the total number of significant figures in \(2.653 \times 10^4\) is **4**.

### Final Answer:
The number of significant figures in \(2.653 \times 10^4\) is **4**.
