Question 281967
how do u solve 7 + 5i / 8 - 7i in standard form?

(7 + 5i)/(8 - 7i) * (8 + 7i)/(8 + 7i) (multiplied top and bottom by conjugate of the denominator)
[(7 + 5i)(8 + 7i)]/[(8 - 7i)(8 + 7i)]
(56 + 49i + 40i + 35i^2)/(64 + 56i - 56i - 49i^2)
(56 + 89i - 35)/(64 + 49)
(21 + 89i)/113
21/113 + (89/113)i
approx. 0.1858 + 0.7876i
