simplify 11(6i-9)

Solution

simplify

11 (6 i - 9)

- 99 + 66 i

Solution steps

11 (6 i - 9)

Apply the distributive law:

a (b - c) = ab - a c

11 (6 i - 9) = 11 \cdot 6 i - 11 \cdot 9

= 11 \cdot 6 i - 11 \cdot 9

Simplify

11 \cdot 6 i - 11 \cdot 9 : 66 i - 99

= 66 i - 99

Rewrite in standard complex form:

- 99 + 66 i

= - 99 + 66 i

(8 x^{5} y^{3})^{\frac{2}{3}}

(2 x - 3 y + z) a + (3 y - 2 x - z) b

\frac{x ^{2} + 11 x + 30}{x ^{2} - 25}

\frac{- 28 x y ^{6} z ^{2}}{4 x ^{5} yz}

\frac{2}{2} - \frac{3}{2}
