Answer 2

The number of digits in the number is ​1005.

Step 1: Find the number of digits in the number.

Given - Square of a number contains 2010 digits.

Use the formula :

If the square of that number is an odd number then $\frac{(n+1)}{2}$.

If the square of that number is an even number then $\frac{n}{2}$ .

Since 2010 is an odd number,

So, Number of digits in the number = $\frac{2010}{2}$

                                                           = $1005$
