If [latex]y=4[/latex], and [latex]x=\sqrt{y}[/latex]. What is the value of x ?
[latex]\sqrt{y}[/latex] is the "square root" symbol. The answer to the above is x=2.
OR, in a reverse fashion using the derived value of x: if [latex]y=x^{2}[/latex] then x is squared or, "raised to the power of 2", or 2X2) so y=4.
Taking it another step:
If [latex]y=9[/latex], and [latex]x=\sqrt{y}[/latex], then x=3, just as if [latex]y=x^{2}[/latex] or, "raised to the power of 2",or 3X3, so y=9.
0r, further:
If [latex]y=8[/latex], and [latex]x=\sqrt[3]{y}[/latex]. What is the value of x ?
[latex]\sqrt[3]{y}[/latex] is the "cube root" symbol. The answer to the above is also x=2.
OR, in a reverse fashion using the derived value of x: [latex]y=x^{3}[/latex] (x is cubed, or "raised to the power of 3", or 2x2x2, so y=8.
