If u = 1 + i and v = 1 - i, what is u + v?

2

Step-by-step explanation:

u = 1+i

v = 1-i

u+v = 1+i + 1-i

= 1+1+i-i

= 2

u + v = 2

Step-by-step explanation:

If v = 1 - i

and u = 1 + i

Then we have to calculate and value of u + v

Now u + v = (1 - i) + (1 + i)

= (-i + i) + (1 + 1) [by adding like terms]

= 0 + 2

= 2

= u + v = 2
