Find the number of Zeros -
`2^222xx5^555`

Options

A. 222
B. 555
C. 777
D. 333

Answer

To find the number of zeros in the expression \(2^{222} \times 5^{555}\), we need to determine how many times we can form the number 10 from the factors of 2 and 5 in the expression. Each pair of one 2 and one 5 will give us one 10, which contributes one zero.

### Step-by-Step Solution:

1. **Identify the powers of 2 and 5**:
- In the expression \(2^{222} \times 5^{555}\), we have:
- Power of 2 = 222
- Power of 5 = 555

2. **Determine the limiting factor**:
- To form a 10, we need one 2 and one 5. The number of 10s we can form is limited by the smaller of the two powers.
- Here, the power of 2 is 222 and the power of 5 is 555.

3. **Calculate the number of pairs**:
- Since we can only form as many pairs as the smaller power, we take the minimum of the two:
\[ \text{Number of pairs} = \min(222, 555) = 222 \]

4. **Conclusion**:
- Therefore, the number of zeros at the end of the number represented by \(2^{222} \times 5^{555}\) is 222.

### Final Answer:
The number of zeros in \(2^{222} \times 5^{555}\) is **222**.
