Answer 1

Answer:

4 number of digits pls mark me as brainliest

Answer 2

Answer:

4

Step-by-step explanation:

Concept= Square root

Given= 7 digit square number

To find= Number of digits after square root

Explanation=

We know that we square a number and the count of digits increase.

Here we have been given a squared number and told to find the count of digits of its square root.

Generally we know that if we square n the value is n^2.

and when we want to know the count of digits of square root of a number it is n/2, where n is the count of squared number.

eg. if we square 11,the value of squared number is 121. Bow if we want to know the original count of the square root we divide the count of 121 which is 3 by 2, 3/2=1.5 since it is decimal we round it off which makes is 2, and our original number was also a two digit number 11.

Similarly we are given 7 digit number so n=7 , we need to know the squared root count so we divide, 7/2=3.5

Rounding off 3.5 is 4.

So the number of digits in the square root of a 7-digit square number is​ 4.
