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

x=49

Step-by-step explanation:

It is given that:

The square root of x = 7 .

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

$\sqrt{x}=7$

(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:

$(\sqrt{x})^2=7^2\\\\i.e.\\\\x=49$

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

x=49
