Which expression is equivalent to (sqrt3 + i)^3?

Anarel [89]

Express √3 + i in polar form:

|√3 + i| = √((√3)² + 1²) = √4 = 2

arg(√3 + i) = arctan(1/√3) = π/6

Then

√3 + i = 2 (cos(π/6) + i sin(π/6))

By DeMoivre's theorem,

(√3 + i)³ = (2 (cos(π/6) + i sin(π/6)))³

… = 2³ (cos(3 • π/6) + i sin(3 • π/6))

… = 8 (cos(π/2) + i sin(π/2))

… = 8i

Consider the polynomial f(x)=2x^5-3x^4+x-6 (x )equals 2 x Superscript 5 Baseline minus 3 x Superscript 4 Baseline plus x minus 6

melamori03 [73]

Answer:

degree of polynomial = 5

leading term = $2x^{5}$

leading coefficient = 2

constant term = -6

Step-by-step explanation:

$f(x) = 2x^{5}-3x^{4}+x-6$

(i) The degree of the polynomial = 5. That is, the highest power of x

(ii) Leading term = $2x^{5}$ . This is the term with the highest power of x.

(iii) Leading Coefficient = 2. That is, the coefficient of the leading term ( $2x^{5}$ )

(iv) Constant term = -6. This is the term that is independent of x or the term in which x doesn't appear.
