Answer:

It's the first choice -4 a^12b^8 / 5.

Step-by-step explanation:

- 8a^8 b^-2 / 10a^-4 b^-10

= -4 a^(8 - -4) b^(-2 - -10) / 5

= -4 a^12b^8 / 5

$\dfrac{-8a^8b^{-2}}{10a^{-4} b^{-10}}$

$= \dfrac{-8}{10} a^8b^{-2} a^{4} b^{10}$

$= -\dfrac{4}{5} a^{12}b^{8}$

Answer: first choice

Help me with this please

Lana71 [14]

Answer:

Step-by-step explanation:

if 45+47=t and t=45+47 t would equal 92 in both

45+47<t than t<45+47

so basically its saying 92<t (92is less than t) and t<92 (t is greater than 92)

he is not right. When you have an equation like that the answer is 92. Its not going to be greater or less than 92. It is 92. It should be t=92

hope that masks some kind of sense. It after 1am here so I apologize if it doesn't sound right...

Given z1 = -3

trasher [3.6K]

Answer:

See explanation

Step-by-step explanation:

The given complex number are:

$z_1=-3\sqrt{3}+3i$

and

$z_2=6\cos 150\degree+6i\sin 150\degree$

When we rewrite $z_1=-3\sqrt{3}+3i$ in complex form, we obtain;

$z_1=r(\cos \theta+i\sin \theta)$

where

$r=\sqrt{(-3\sqrt{3})^2+3^2 }=\sqrt{36}=6$

and

$\theta=tan^{-1}(\frac{y}{x})$

$\implies \theta=tan^{-1}(\frac{-3\sqrt{3}}{3})=150\degree$

Hence,

$z_1=6(\cos 150\degree+i\sin 150\degree)$

$z_1=6\cos 150\degree+6i\sin 150\degree$

Hence

$z_1=z_2$
