simplify (-i/2)^2

Solution

simplify

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

Solution

- \frac{1}{4}

+1

Decimal Notation

- 0.25

Solution steps

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

Apply exponent rule:

(- a)^{n} = a^{n},

if

n

is even

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

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

Apply exponent rule:

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

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

2^{2} = 4

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

Apply imaginary number rule:

i^{2} = - 1

= \frac{- 1}{4}

Apply the fraction rule:

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

= - \frac{1}{4}
