The value of a and b in the product of 4+3i and its conjugate in the format a + bi are 25 and 0.
<h3>What is conjugate?</h3>
The conjugate is where we change the sign in the middle of two terms. For example:
3y + 1
conjugate of 3y + 1 is 3y - 1.
Therefore, the conjugate of 4 + 3i is 4 - 3i.
The product of 4 + 3i and its conjugate is as follows:
(4 + 3i)(4 - 3i) = 16 - 12i + 12i - 9(i)²
Therefore,
16 - 9i²
i² = -1
Hence,
16 - 9(-1) = 25
It can be written in the form a complex form → (25 + 0.i)
Therefore, a = 25 and b = 0.
