Question

If u = (1 + i ) and v = (1 − i ), what is uv? 1 -4 -4i 4

Answer 1

It's 2

Explanation:

Answer 2

The value of the product of u and v is
`2`.

Explanation:

Given: The value of
`u=1+i` and
`v=1-i`

To find: The value of
`uv`.

Solution: It is given that the value of of
`u=1+i` and
`v=1-i`, then the product is given as:

`uv=(1+i)(1-i)`

`uv=(1)^2-(i)^2` (Using identity
`a^2-b^2=(a+b)(a-b)`)

`uv=1-(-1)`

`uv=2`

Thus, the value of the product of u and v is
`2`.
