If A =`{1,2,3,4,5,....10}` , then the number of all possible subsets of A .

Answer

To find the number of all possible subsets of the set A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Set**:
The given set A is {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

2. **Count the Number of Elements**:
Count the elements in set A. There are 10 elements in total.

3. **Use the Subset Formula**:
The formula to calculate the number of subsets of a set is \(2^n\), where \(n\) is the number of elements in the set.

4. **Substitute the Value of n**:
Here, \(n = 10\). So, we substitute this value into the formula:
\[ \text{Number of subsets} = 2^{10} \]

5. **Calculate \(2^{10}\)**:
Now, we need to calculate \(2^{10}\):
\[ 2^{10} = 1024 \]

6. **Conclusion**:
Therefore, the number of all possible subsets of set A is 1024.

### Final Answer:
The number of all possible subsets of A is **1024**.
