Respuesta :
(5+3i)(8-2i). We will FOIL this out like anything else. 5*8 = 40; 5*2i = 10i; 3i*8 = 24i; 3i*-2i = -6i^2. Putting that all together we have 40+10i+24i-6i^2. Simplifying we have 40+34i-6i^2. i^2 = -1, s0 -6*-1=6. Now let's rewrite. 40+34i+6 = 46 + 34i. That's the product.
Answer: The required standard form of the product is [tex]46+14i.[/tex]
Step-by-step explanation: We are given to find the product of the following two complex numbers and write the answer is standard complex number form.
[tex](5+3i)(8-2i).[/tex]
We know that
a complex number z can be written in standard complex number form as follows :
[tex]z=a+bi.[/tex]
Now,
[tex](5+3i)(8-2i)\\\\=5\times8-5\times2i+3i\times8-3i\times2i\\\\=40-10i+24i-6i^2\\\\=40+14i+6~~~~~~~~~~~[\textup{since }i^2=-1]\\\\=46+14i.[/tex]
Thus, the required standard form of the product is [tex]46+14i.[/tex]
