(-3+2iroot48)(-5-4iroot12)
iVinArrow [24]

For this case we must simplify the following expression:

(-3 + 2i \sqrt {48}) (- 5-4i \sqrt {12})

Rewriting:

(-3 + 2i \sqrt {4 ^ 2 * 3}) (- 5-4i \sqrt {2 ^ 2 * 3}) =\\(-3 + 2 * 4i \sqrt {3}) (- 5-4 * 2i \sqrt {3}) =\\(-3 + 8i \sqrt {3}) (- 5-8i \sqrt {3}) =

We apply distributive property:

- * - = +\\- * + = -\\15 + 24i \sqrt {3} -40i \sqrt {3} - (8i \sqrt {3}) ^ 2 =\\15 + 24i \sqrt {3} -40i \sqrt {3} -64i ^ 2 * 3 =

We have toi ^ 2 = -1:

15 + 24i \sqrt {3} -40i \sqrt {3} + 192 =

Adding similar terms:

207-16i \sqrt {3}

Answer:

207-16i \sqrt {3}

Como Determinar a equação da reta que passa pelos pontos A(-1, -2) e B(5,2)
Komok [63]

Answer:

A equação da reta é dada por: y = \frac{2}{3}x - \frac{4}{3}

Step-by-step explanation:

Equação de uma reta:

A equação de uma reta tem o seguinte formato:

y = ax + b

Em que a é o coeficiente angular e b é o coeficiente linear.

Coeficiente angular:

Com posse de dois pontos, o coeficiente angular é dado pela mudança em y dividida pela mudança em x.

A(-1, -2) e B(5,2)

Mudança em y: 2 - (-2) = 2 + 2 = 4

Mudança em x: 5 - (-1) = 5 + 1 = 6

Coeficiente angular: m = \frac{4}{6} = \frac{2}{3}

Então:

y = \frac{2}{3}x + b

Coeficiente linear:

Substituindo um ponto na equação, encontra-se o coeficiente linear.

B(5,2)

Quando x = 5, y = 2. Então:

y = \frac{2}{3}x + b

2 = \frac{2}{3}5 + b

b = 2 - \frac{10}{3} = \frac{6}{3} - \frac{10}{3} = -\frac{4}{3}

Então:

y = \frac{2}{3}x - \frac{4}{3}
