You asked:

Evaluate the expression: \(16 - {\cos\left( α \right)}^{28}\)

MathBot Answer:

\[16 - {\cos\left( α \right)}^{28} = 16 - \cos^{28}{\left(α \right)}\]

Factored

\[16 - {\cos\left( α \right)}^{28} = - \left(\cos^{7}{\left(α \right)} - 2\right) \left(\cos^{7}{\left(α \right)} + 2\right) \left(\cos^{14}{\left(α \right)} + 4\right)\]
