Answer:

[tex]\sf \dfrac{7}{12}[/tex]

explanation:

[tex]\hookrightarrow \sf \dfrac{1}{4}-2\sqrt[3]{-\dfrac{1}{216}}[/tex]

we should know the following [tex]\sqrt[3]{-\dfrac{1}{216} } = -\dfrac{1}{6}[/tex]

[tex]\hookrightarrow \sf \dfrac{1}{4}-\left(2 * -\dfrac{1}{6}\right)[/tex]

[tex]\hookrightarrow \sf \dfrac{1}{4}-\left(-\dfrac{1}{3}\right)[/tex]

[tex]\hookrightarrow \sf \dfrac{1}{4}+\dfrac{1}{3}[/tex]

[tex]\hookrightarrow \sf \dfrac{7}{12}[/tex]

Answer:

[tex]\frac{7}{12}[/tex]

Step-by-step explanation:

Well, I'm not sure how you get your answer but see below for steps for how i get my answer;

[tex]\frac{1}{4}-2\sqrt[3]{-\frac{1}{216}}[/tex]

[tex]2\sqrt[3]{-\frac{1}{216}}=-2*\frac{1}{6}[/tex]

[tex]=\frac{1}{4}-(-2*\frac{1}{6})[/tex]

[tex]\frac{1}{4}-(-2*\frac{1}{6})=\frac{7}{12}[/tex]

[tex]=\frac{7}{12}[/tex]

Thus, the answer is 7/12
