(9 - 10 i) (- 8 + 3 i)

- 42 + 107 i

Solution steps

(9 - 10 i) (- 8 + 3 i)

Apply complex arithmetic rule:

(a + bi) (c + d i) = (a c - b d) + (a d + b c) i

= (9 (- 8) - (- 10) \cdot 3) + (9 \cdot 3 - 10 (- 8)) i

Simplify

(9 (- 8) - (- 10) \cdot 3) + (9 \cdot 3 - 10 (- 8)) i : - 42 + 107 i

= - 42 + 107 i

(0.06)^{3}

\frac{( 3 π )}{2}

\frac{π}{30}

x, 9 (x + 1) = 25 + x
