Let z = √3 + i. Compute the modulus and argument of z :
|z| = √((√3)² + 1²) = √4 = 2
arg(z) = arctan(1/√3) = π/6 = 30°
Then
z = √3 + i = 2 (cos(30°) + i sin(30°))
For this case we have the following functions:
We must find
By definition of composition of functions we have to:
So:
We have different signs subtracted and the sign of the major is placed.
Finally we have to:
ANswer:
Answer:
40
Step-by-step explanation:
5√64 = 5 x 8 = 40
Answer:
Step-by-step explanation:
Rewrite:
Cube both sides:
Divide both sides by 729:
Take the square root of both sides:
Hope this helps!
