Answer:
The sum is 4 i√2
Step-by-step explanation:
Both the numbers √-2 and √-18 are imaginary number and thus can be presented as
i√2 and i√18
On simplifying, the i√18 can be written as i√( 9 x 2)
Taking out square root of 9 we get-
3i√2
Thus the summation of i√2 and i√18 can be written as
i√2 + 3i√2
= 4 i√2
