expand ((2i-2)/n)^2

Solution

expand

(\frac{2 i - 2}{n})^{2}

Solution

- \frac{8 i}{n ^{2}}

Solution steps

(\frac{2 i - 2}{n})^{2}

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{( 2 i - 2 ) ^{2}}{n ^{2}}

(2 i - 2)^{2} = - 8 i

= \frac{- 8 i}{n ^{2}}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{8 i}{n ^{2}}
