How to find the square root of complex numbers?? Find the square root of (6+8i) ??

ivann1987 [24]

Answer:

$2 \sqrt{2} + i \sqrt{2}$

Step-by-step explanation:

The square of a complex number is a complex number. Here, we have:

${(a + bi)}^{2} = 6 + 8i$

${a}^{2} + 2abi - {b}^{2} = 6 + 8i$

We then have this system of equations:

${a}^{2} - {b}^{2} = 6$

$2ab = 8$

Solving this system:

$ab = 4$

$b = \frac{4}{a}$

${a}^{2} - {( \frac{4}{a}) }^{2} = 6$

${a}^{2} - \frac{16}{ {a}^{2} } = 6$

${a}^{4} - 16 = 6{a}^{2}$

${a}^{4} - 6 {a}^{2} - 16 = 0$

$( {a}^{2} - 8)( {a}^{2} + 2) = 0$

${a}^{2} = 8$

$a = 2 \sqrt{2}$

$b = \frac{4}{2 \sqrt{2} } = \sqrt{2}$

Yoko received a $70 gift card for a coffee store. She used it in buying some coffee that cost $8.62 per pound. After buying the

Jlenok [28]

Answer:

She bought 5 pounds of coffee.

Step-by-step explanation:

We are looking for how many pounds so pounds would be your x.

each pound costs $8.62.

You are taking the money she payed for the coffee away from the $70 she received.

Set up your equation

70 - 8.62x = 26.90

Solve for x

Subtract 70 from both sides 70-70 (Cancels out) - 8.62x= 26.90-70

-8.62x = -43.10

Divide -8.62 from each side. -8.62/-8.62(cancels out) x = -43.10/-8.62 (two negative numbers multiplied or divided by each other makes a positive)

x=5
