2 times 9+7

If the square root of x = 7, then x must be equal to:

It is given that:

The square root of x = 7 .

i.e. algebraically this expression is given as follows:

(We know that the term under the radical sign i.e. the square root sign is known as a radicand )

Now, on taking square on both the sides of the equation we have:

        Hence, the value of x which is obtained from the given equation is:
