simplify ((2i)/n)^2

Solution

simplify

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

Solution

- \frac{4}{n ^{2}}

Solution steps

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

Apply exponent rule:

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

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

Simplify

(2 i)^{2} : 4 i^{2}

= \frac{4 i ^{2}}{n ^{2}}

Simplify

4 i^{2} : - 4

= \frac{- 4}{n ^{2}}

Apply the fraction rule:

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

= - \frac{4}{n ^{2}}
