if a number contains 3 zeros at the end how many zeros will its square have

Answer 1

Solution:

Let's start from an example: square of 10 = 100

[note a number contains 1 zero then its square have 2 zeroes]

Now let's consider another example: square of 100 = 10000

[note a number contains 2 zeroes then its square have 4 zeroes]

Now let's talk about a number contains 3 zeroes at the end

square of 1000 = 1000000

Conclusion: every time zeroes get double. Then the answer is 6 zeroes.

Hope this help!
