Hint: Here we have to only draw a square root table and then from that we will get the value of \[\sqrt 7 \] by only looking over it.
Complete step-by-step answer:
As we know from the definition of square root that if there are two numbers a and b such that a\[ \times \]a = b.
Then the square root of the number b will be equal to a.
So, let us draw the square root table for numbers 1 to 20.
So, from the above table we can see that if the number is 7 then its square root is 2.646.
Hence, the value of \[\sqrt 7 \] is 2.646.
Note: Whenever we come up with this type of problem if we are asked to find the root of any number by any particular method like here, we have to find a square root of 7 by square root table. So, we draw the square root table from number 1 to 20 to get the required.
