Answer:

4*sqrt 10

Step-by-step explanation:

5-1=4

6--6=12

12^2 + 4^2 = 160

sqrt 160 = 4*sqrt 10

4*sqrt10

Is 4 kilograms is egual to 4000mgs
Zigmanuir [339]
No.
So, there are 1000 milligrams in one gram, making the 4000 mgs equal to 4 grams.
There are 1000 grams in one kilogram, so 4 kilograms is equal to 4000 grams.

4000 =/= 4
So, 4 kilograms and 4000 milligrams are not equal.

The polar form of the complex numbers are z₁ = 6 · e^{i\,\frac{11\pi}{6} } and z₂ = √2 · e^{i\,\frac{3\pi}{4} }. The multiplication of the numbers is z₁ · z₂ = 6√2 · e^{i\,\frac{31\pi}{12} }, the division of the numbers is z₁ / z₂ = 3√2 · e^{i\,\frac{13\pi}{12} } and the reciprocal of a number is 1 / z₁ = (1 / 6) · e^{-i\,\frac{11\pi}{6} }.

<h3>How to find complex numbers in polar forms and make operations with them </h3>

In this problem we find two complex numbers in rectangular form (z = a + i b), whose polar form has to be found. The complex form is described below:

z = r · e^{i\,\theta}

Where:

  • r - Norm
  • θ - Direction, in radians.

The magnitude is determined by Pythagorean theorem:

r = √(a² + b²)

And the direction by inverse trigonometric functions:

θ = tan⁻¹ (b / a)

Polar form offers a quicker manner to perform multiplication and division of complex numbers. Thus:

Multiplication

z₁ · z₂ = r₁ · r₂ · e^{i\,(\theta_1 + \theta_2)}

Division

z₁ / z₂ = (r₁ / r₂) · e^{i\,\frac{\theta_{1}}{\theta_{2}} }

First, determine the magnitudes of each complex number:

r₁ = √[(3√3)² + (- 3)²]

r₁ = 6

r₂ = √[(- 1)² + 1²]

r₂ = √2

Second, determine the directions of each complex number:

θ₁ = 11π / 6

θ₂ = 3π / 4

Third, write the complex numbers in polar form:

z₁ = 6 · e^{i\,\frac{11\pi}{6} }

z₂ = √2 · e^{i\,\frac{3\pi}{4} }

Fourth, find the multiplication of the complex numbers:

z₁ · z₂ = 6√2 · e^{i\,\frac{31\pi}{12} }

Fifth, find the division of the complex numbers:

z₁ / z₂ = 3√2 · e^{i\,\frac{13\pi}{12} }

Sixth, find the reciprocal of the complex number:

1 / z₁ = (1 / 6) · e^{-i\,\frac{11\pi}{6} }
