What answer is this?

Answer:

option B

$\frac{31}{50}-\frac{4}{25} i$

Step-by-step explanation:

Given in the question a complex fraction

<h3>Step1</h3>

To divide complex numbers, you must multiply by the conjugate. To find the conjugate of a complex number all you have to do is change the sign between the two terms in the denominator.

$\frac{5+4i}{6+8i}(\frac{6-8i}{6-8i})$

<h3>Step2</h3>

Distribute (or FOIL) in both the numerator and denominator to remove the parenthesis.

$\frac{30+24i-40i-32i²}{36-64i^{2} }$

<h3>Step3</h3>

Simplify the powers of i, specifically remember that i² = –1.

$\frac{62-16i}{36+64}$

<h3>Step4</h3>

$\frac{62}{100}-\frac{16i}{100}$

<h3>Step5</h3>

simply

$\frac{31}{50}-\frac{4}{25}i$

If (1/a)+(1/b)=10 what is the value of a+b?

Goshia [24]

B) 2/5

I think, if a and b are the same (coz then they would both equal 0.2)
