Answer:
1 | 5/6 hours is the correct answer
Step-by-step explanation:
1 1/2 + 1/3
1 3/6 + 2/6
1 5/6
9 1/2 is the simplest form. If you are looking for an improper fraction than it would be 19/2. Does this help?
The statement that is true about mass are:
- One kilogram is 1,000 times greater than one gram.
- Kilograms are greater than grams
<h3>What is mass?</h3>
The mass is the physical measuring quantity that measures the weight or body inertia of a substance.
It also pinpoints the strength of an object's gravitational abstraction to other bodies.
The unit of mass can be expressed in;
A kilogram usually contains 1000 grams. Thus, we can conclude that:
- One kilogram is 1,000 times greater than one gram.
- Kilograms are greater than grams.

If we have the complex number ⇒ z = a ( cos θ + i sin θ)
∴
![\sqrt[n]{z} = \sqrt[n]{a} \ (cos \ \frac{\theta + 360K}{n} + i \ sin \ \frac{\theta +360k}{n} )](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7Bz%7D%20%3D%20%20%5Csqrt%5Bn%5D%7Ba%7D%20%5C%20%28cos%20%5C%20%20%5Cfrac%7B%5Ctheta%20%2B%20360K%7D%7Bn%7D%20%2B%20i%20%5C%20sin%20%5C%20%5Cfrac%7B%5Ctheta%20%2B360k%7D%7Bn%7D%20%29)

For The given complex number <span>⇒ z = 81(cos(3π/8) + i sin(3π/8))
</span>
Part (A) <span>
find the modulus for all of the fourth roots </span>
<span>∴ The modulus of the given complex number = l z l = 81
</span>
∴ The modulus of the fourth root =
Part (b) find the angle for each of the four roots
The angle of the given complex number =

There is four roots and the angle between each root =

The angle of the first root =

The angle of the second root =

The angle of the third root =

The angle of the fourth root =
Part (C): find all of the fourth roots of this
The first root =

The second root =

The third root =

The fourth root =
