Answer 2

Multiplying Complex Numbers

To multiply the complex numbers (5-3i) and (5+3i), we can use the formula: (a+bi)(c+di) = (ac - bd) + (ad + bc)i. Let's apply this formula to the given complex numbers.

Given complex numbers: - First complex number: 5-3i - Second complex number: 5+3i

Solution

Using the formula (a+bi)(c+di) = (ac - bd) + (ad + bc)i, we get: (5-3i)(5+3i) = (5*5 - (-3*3)) + (5*3 + (-3*5))i = (25 + 9) + (15 - 15)i = 34 + 0i = 34

So, the product of (5-3i) and (5+3i) is 34.

This result is obtained by applying the formula for multiplying complex numbers
