Question

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

0.256
0.0256
0.4
0.04

s.r square root

Answer 1

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.

Answer:

4

Answer 2

4

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.
