simplify 8(1-i)-(-4.11i)+2(30-12i)

simplify

8 (1 - i) - (- 4.11 i) + 2 (30 - 12 i)

68 - 27.89 i

Solution steps

8 (1 - i) - (- 4.11 i) + 2 (30 - 12 i)

Apply rule:

a - (- b) = a + b

8 (1 - i) - (- 4.11 i) = 8 (1 - i) + 4.11 i

= 8 (1 - i) + 4.11 i + 2 (30 - 12 i)

Expand

8 (1 - i) : 8 - 8 i

= 8 - 8 i + 4.11 i + 2 (30 - 12 i)

Expand

2 (30 - 12 i) : 60 - 24 i

= 8 - 8 i + 4.11 i + 60 - 24 i

Group like terms

= - 8 i + 4.11 i - 24 i + 8 + 60

Add similar elements:

- 8 i + 4.11 i - 24 i = - 27.89 i

= - 27.89 i + 8 + 60

Add the numbers:

8 + 60 = 68

= - 27.89 i + 68

Rewrite in standard complex form:

68 - 27.89 i

= 68 - 27.89 i

\frac{e ^{- 3 s}}{( s - 1 ) ^{3}}

\frac{x ^{2} - 25}{x ^{4}}

\frac{1}{( 3 + 2 x ) ^{2}}
