Answer:

X^2 + 5x + 6

Step-by-step explanation:

(X times X) + (x times 2) + (x times 3) + ( 3 times 2)

X^2 + (2x) + (3x) + 6

combind like terms

Step-by-step explanation:

This is the basics of FOIL

To answer this question, you need to know FOILING.

( a + b ) ( a + b )

= aa + ab + ba + bb

( x + 3 ) ( x + 2 )

= x^2 + 2x + 3x + 6 Now simplify

= x^2 + 5x + 6

Use DeMoivre's Theorem to find the indicated power of the complex number. Write answers in rectangular form. [one half (cosine

Morgarella [4.7K]

Answer:

$(\, \cos(\frac{\pi}{16}) + i\sin(\frac{\pi}{16}) \,)^{1/2} = \cos(\frac{\pi}{32}) + i\sin(\frac{\pi}{32}) = 0.99 + i0.09$

Step-by-step explanation:

The complex number given is

$z = (\, \cos(\frac{\pi}{16}) + i\sin(\frac{\pi}{16}) \,)^{1/2}$

Now, remember that the DeMoivre's theorem states that

$( \cos(x) + i\sin(x) )^n = \cos(nx) + i\sin(nx)$

Then for this case we have that

$(\, \cos(\frac{\pi}{16}) + i\sin(\frac{\pi}{16}) \,)^{1/2} = \cos(\frac{\pi}{32}) + i\sin(\frac{\pi}{32}) = 0.99 + i0.09$

X^-n = 1/x^n
Your fraction becomes:
1/ {(m^5 t^2)(27m^6t^3)} now combine the powers in the denominator
1/ (27 m^11 t^5)
