simplify (-1-isqrt(3))^{-4}

simplify

(- 1 - i 3)^{- 4}

- \frac{1}{32} + \frac{3}{32} i

Solution steps

(- 1 - i 3)^{- 4}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

(- 1 - i 3)^{- 4} = \frac{1}{( - 1 - i 3 ) ^{4}}

= \frac{1}{( - 1 - i 3 ) ^{4}}

Expand

(- 1 - i 3)^{4} : - 83 i - 8

= \frac{1}{- 8 3 i - 8}

Rewrite

- 83 i - 8

in standard complex form:

- 8 - 83 i

= \frac{1}{- 8 - 8 3 i}

Multiply by the conjugate

\frac{- 8 + 8 3 i}{- 8 + 8 3 i}

= \frac{1 \cdot ( - 8 + 8 3 i )}{( - 8 - 8 3 i ) ( - 8 + 8 3 i )}

Simplify

\frac{1 \cdot ( - 8 + 8 3 i )}{( - 8 - 8 3 i ) ( - 8 + 8 3 i )} : \frac{- 8 + 8 3 i}{256}

= \frac{- 8 + 8 3 i}{256}

Apply the fraction rule:

\frac{a + bi}{c} = \frac{a}{c} + \frac{b}{c} i

= \frac{- 8}{256} + \frac{8 3}{256} i

Simplify

\frac{- 8}{256} + \frac{8 3}{256} i : - \frac{1}{32} + \frac{3}{32} i

= - \frac{1}{32} + \frac{3}{32} i

1 + cot^{2} (x)

\frac{35000}{4 π \cdot ( 7.5 \cdot 1 0 ^{- 3} ) ^{2}}

\frac{sec ( x )}{tan ( x )}
