展开 (a-12b)+(-b+12a)i

解答

展开

(a - 12 b) + (- b + 12 a) i

(a - 12 b) + (- b + 12 a) i

求解步骤

(a - 12 b) + (- b + 12 a) i

使用法则:

(a) = a

(a - 12 b) = a - 12 b

= a - 12 b + (- b + 12 a) i

= a - 12 b + i (- b + 12 a)

展开

i (- b + 12 a) : - bi + 12 ai

= a - 12 b - bi + 12 ai

Rewrite in standard complex form:

(a - 12 b) + (- b + 12 a) i

= (a - 12 b) + (- b + 12 a) i
