To find the number of zeros in the square of 400, we need to determine the number of factors of 10 in the product. Since 10 can be expressed as 2 x 5, we need to find the number of factors of 2 and 5 in the product.
Prime factorization of 400:
400 = 2 x 2 x 2 x 2 x 5 x 5
Number of factors of 2 in 400:
We can see that there are four factors of 2 in the prime factorization of 400. So, we have four 2s in the product.
Number of factors of 5 in 400:
There are two factors of 5 in the prime factorization of 400. So, we have two 5s in the product.
Since we need to find the number of factors of 10, which is 2 x 5, we need to determine the minimum of the number of factors of 2 and 5. In this case, we have two factors of 5, which means we can form two pairs of 2 and 5 to get the factors of 10.
Therefore, the number of zeros in the square of 400 is equal to the minimum of the number of factors of 2 and 5, which is 2. So, the correct answer is option A) 2.
