Answer:
u+v=7-7i
u-v=3+3i
Step-by-step explanation:
u+v
(5-2i)+(2-5i)
Put like terms together:
(5+2)+(-2i-5i)
Simplify:
7+-7i
7-7i
u-v
(5-2i)-(2-5i)
Distribute:
(5-2i)+(-2+5i)
Put like terms together:
(5-2)+(-2i+5i)
3+3i
The value of u +v = 7 -7i and u-v = 3 + 3i.
What are complex numbers?
The numbers that can be expressed in the form of a + ib are called Complex numbers, i is called the iota, whose value is equal to the square root of -1.
These are imaginary numbers.
The complex numbers are
u = 5 − 2i
v = 2 − 5i
The sum of the complex number is obtained as follows:
u + v = 5 - 2i +2 - 5i
The imaginary part is grouped with imaginary part and the real numbers are grouped together.
u +v = 7 -7i
The output of addition is 7 -7i
The difference of the complex numbers is obtained as follows
and u− v = 5-2i - 2 +5i
u-v = 3 + 3i
The output of Subtraction is 3 + 3i
The mathematical operations are normally performed in complex numbers, the coefficients of the imaginary part are added and subtracted by the imaginary part only.
