化简 sqrt(-4)+2sqrt(9)+i-8+2/(1-i)

解答

化简

- 4 + 29 + i - 8 + \frac{2}{1 - i}

- 1 + 4 i

求解步骤

- 4 + 29 + i - 8 + \frac{2}{1 - i}

Rewrite in standard complex form:

- 4 + 29 - 8 + i + \frac{2}{1 - i}

= - 4 + 29 - 8 + i + \frac{2}{1 - i}

化简

- 4 + 29 - 8 + i : 2 i - 2 + i

= 2 i - 2 + i + \frac{2}{1 - i}

化简

(2 i - 2) + i + \frac{2}{1 - i} : 4 i - 1

= 4 i - 1

Rewrite in standard complex form:

- 1 + 4 i

= - 1 + 4 i
