1+ 8n - 6n = 13 + 6n -6n;     1 - 1 + 2n = 13 - 1;   2÷ 2n = 12 ÷2;   n = 6

The answer is n=6

Write the complex number 1 +i/1 -i into polar form​
IRINA_888 [86]

Answer:

cos(pi/2) + i sin (pi/2)

Step-by-step explanation:

(1+i)/ (1-i)

Multiply top and bottom by (1+i)

(1+i) (1+i)/ (1-i)(1+i)

Foil the top (1+i)(1+i) = 1 +2i +i^2 = 1 +2i -1 = 2i

Foil the bottom ( 1+i)(1-i) = 1 - i^2 = 1 - (-1) =2

2i/2 = i

the magnitude is (0^2+1^2) = 1

The angle is tan^-1( 1/0) = pi/2

cos(pi/2) + i sin (pi/2)

Using PEMDAS
(Parenthesis)(Exponents)(Multiplication/Division)(Addition/Subtration)
So:
\frac{5}{8} * ((54-22)-45) =  \frac{5}{8}*(32-45) =  \frac{5}{8}(-13)
=  \frac{-65}{8}= -8.125
