Question

If a perfect square number consists of 7 digits, then how many digits does its square root consist?​

Answer 1

Answer: 4 digits

Step-by-step explanation:

For even number 'n' the square root will contain n/2 digits

and for odd number 'n' the square root will contain (n+1)/2 digits

If Perfect square contains 7 digits then the square root will consist of 4 digits

7 is an odd number that means its root will have n+1/2 digits

= (7+1)/2

=8/2

=4
