x2≤64
-6
the answer is -8<x<8.
x2 = 16take the root square for both sides the result will be :X = +4 or -4
x2 ≥ 0 is one possible answer.
x2≤64
if x2 ≠ 16, then: {x | x ∈ ℜ, x ∉ (4, -4)}
x2 square root of x is an expression, not an equation or inequality. It, therefore, has no answer.
-6
x^2<25
The question cannot be answered because there is no inequality there!
the answer is -8<x<8.
If x2 < 25 Then: |x| < 5 -5 < x < 5
If x2 = 16 then this is not written as an inequality.An inequality tells us that one thing is not equal to another.The above is an equation, because it is telling us that one thing is equal to another.If x2 = 16 then x = 4 & -4.
Instead of the answer being a curve, it is a region. For example, if y > x2 + 4, the answer is not the parabola y = x2 + 4. Instead it is the region above the parabola (as if the bowl were filled with something.)
