(1/x)^3+(2/8)^3
You asked:
Evaluate the expression: \({\left( \frac{1}{x} \right)}^{3} + {\left( \frac{2}{8} \right)}^{3}\)
MathBot Answer:
Evaluated
\(\displaystyle {\left( \frac{1}{x} \right)}^{3} + {\left( \frac{2}{8} \right)}^{3} = \frac{1}{64} + \frac{1}{x^{3}} \)
Factored
\[{\left( \frac{1}{x} \right)}^{3} + {\left( \frac{2}{8} \right)}^{3} = \frac{\left(x + 4\right) \left(x^{2} - 4 x + 16\right)}{64 x^{3}}\]
