\[x^2 > 36\]
well I'm not giving direct answers because that's against code of conduct... but all you have to do is to square root both sides
\[\sqrt{x^2}>\sqrt{36}\]
then take the square root of x^2 and 36
OpenStudy (anonymous):
okay
OpenStudy (anonymous):
okay
OpenStudy (usukidoll):

|dw:1437632210874:dw| I just re-wrote it to exponential form to make it a bit easier to see
what is 2 divided by 2 ?
OpenStudy (anonymous):
The definition of
\[x^2= \pm \sqrt{x}\]
OpenStudy (anonymous):
so if
\[X^2 ={25}\]
then
\[x=\pm \sqrt{25} = x=\pm5\]
OpenStudy (anonymous):
