Question

what is the value of x if x^2=10

Please explain

Answer 1

For this case we have the following equation:

$x ^ 2 = 10$

We must find the value of the variable "x", for this:

We apply square root to both sides of the equation:

$x = \pm \sqrt {10}$

Thus, the solutions of the equation are:

$x_ {1} = + \sqrt {10}\\x_ {2} = - \sqrt {10}$

Answer:

$x_ {1} = + \sqrt {10}\\x_ {2} = - \sqrt {10}$
