I'm going to attempt to ask an educated algebra question. Please forgive a bad translation.
Inequalities and Powers/Roots.
Legend:
() <-Power
[] <-Square Root
Solve:
the square of x is less than 4
x(2)<4
would this translate to
x is less then the positive/negative of the square root of 4.
x<+/>-[4]
or
x<2 and x>-2
[edit1]
-2<x<2
[/edit1]
??????????????????????????
My book doesn't address this type of inequality, and would really like to know this.
