Simplify: -3(5x-6)+4(5x-2)+6x

Write the real form of each complex equation.

Lerok [7]

Answer:

Step-by-step explanation:

Given

(a) $z=4\cos (\theta )+9i\sin (\theta )$

$Re(z)=4\cos \theta$

$Im(z)=9\sin \theta$

(b) $z=6\cos (\theta )+i\sin (\theta )$

$Re(z)=6\cos \theta$

$Im(z)=\sin \theta$

(c) $z=\sqrt{5}\cos (\theta )+\sqrt{10}i\sin (\theta )$

$Re(z)=\sqrt{5}\cos (\theta )$

$Im(z)=\sqrt{10}\sin (\theta )$

(d) $z=5-2i+4\cos (\theta )+7i\sin (\theta )$

$z=5+4\cos \theta +i(7\sin \theta -2)$

$Re(z)=5+4\cos \theta$

$Im(z)=7\sin \theta -2$

tester [92]

Answer:

4^15

Step-by-step explanation:

(4^3)^5

We know a^b^c = a^(b*c)

(4^3)^5 = 4^(3*5) = 4^15
