Question

If s.r 16 = x , then what is the value of x ?

Answer 1

Answer:

4

Step-by-step explanation:

The square root of a number is the same number multiplied by itself. In the case of 16, 4x4 equals 16. So 4 is being used twice making it the square root of 16.

Answer 2

For this case, we have the following equation:

$\sqrt {16} = x$

We must find the value of the variable "x":

We raise both sides of the equation to the square:

$(\sqrt {16}) ^ 2 = x ^ 2\\16 = x ^ 2$

We know that:

$(4) (4) = 16\\(-4) (- 4) = 16$

Therefore x can take values of:

4 and -4

Specifically, the square root of 16 is 4.

4
