Move the decimal place over as many times as the number that ten is rooted by like it would be 990,000,000 + 5,500,000 = 995,500,000 or (if they want it in the form for future reference) 995.5×10^6

The sum of two numbers is 0. Twice the smaller number subtracted from 3 times the larger number is 10. Let x represent the large
Bezzdna [24]

Answer:

x+y=0 and 3x-2y=10

Step-by-step explanation

Let the numbers be x and y.

The sum of the two numbers is 0

\implies \: x + y =0

Letting the smaller number be y and the

larger number be x:

twice the smaller number

\implies \: 2y

Also, 3 times the larger number

\implies \: 3x

Now ,twice the smaller number subtracted from 3 times the larger number is 10.

\implies \: 3x - 2y = 10

Therefore the equations are

x + y =0

and

3x  - 2y =10

Use DeMoivre's Theorem to find (3cis*pi/6)^3
Sonbull [250]

The correct value of (3cis(pi/6))³ is 27i.

<h3>What is Complex Number?</h3>

Complex numbers are numbers that consist of two parts — a real number and an imaginary number. Complex numbers are the building blocks of more intricate math, such as algebra.

Given the complex number in polar coordinate expressed as

z = r(cos∅+isin∅)

zⁿ =  {r(cos∅+isin∅)}ⁿ

According to DeMoivre’s Theorem;

zⁿ =  rⁿ(cosn∅+isinn∅)

Given the complex number;

(3cis(pi/6))³

= {3(cosπ/6 + isinπ/6)}³

Using  DeMoivre’s Theorem;

= 3³(cos3π/6 + isin3π/6)

=  3³(cosπ/2 + isinπ/2)

= 3³(0 + i(1))

= 27i

Thus, the correct value of (3cis(pi/6))³ is 27i.
