Find the fourth roots of 256(cos 240° + i sin 240°).
Mashcka [7]

Answer with Step-by-step explanation:

We are given that

We have to find the fourth roots of given complex number.

(256)^{\frac{1}{4}}=(4^4)^{\frac{1}{4}}=4^^{\frac{1}{4}\times 4}=4

By using the formula

(a^b)^x=a^{bx}

\theta=240^{\circ}

\theta=\frac{240}{4}=60^{\circ}

Angle of rotation=\frac{360}{4}=90^{\circ}

Therefore, the four roots of given complex number are

4(cos 60^{\circ}+i sin60^{\circ})

4(cos150^{\circ}+i sin150^{\circ})

4(cos240^{\circ}+isin 240^{\circ})

4(cos330^{\circ}+i sin330^{\circ})

Match each operation involving f(x) and g(x) to its answer.
galben [10]
F(x)=1-x² and g(x)=√(11-4x)

(g+f)(2)=>

 1-(2)²+√(11-4(2))

=√3-3

(f/g)(-1)

(1-(-1)²)/(√(11-4(-1))

=0

(g-f)(-1)

√(11-4*-1)-(1-(-1)²

=√15

(g×f)(2)

1-(2)²×√(11-4(2))

-3√3
