Option B:
Sum of
and
is
.
Solution:
Given data:
and ![\sqrt{-18}](https://tex.z-dn.net/?f=%5Csqrt%7B-18%7D)
To find the sum of
and
.
Sum of
and ![\sqrt{-18}](https://tex.z-dn.net/?f=%5Csqrt%7B-18%7D)
![=\sqrt{-2} +\sqrt{-18}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B-2%7D%20%2B%5Csqrt%7B-18%7D)
![=\sqrt{-2} +\sqrt{-2\times 9}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B-2%7D%20%2B%5Csqrt%7B-2%5Ctimes%209%7D)
![=\sqrt{-2} +\sqrt{-2\times 3^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B-2%7D%20%2B%5Csqrt%7B-2%5Ctimes%203%5E2%7D)
![=\sqrt{-2} +3\sqrt{-2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B-2%7D%20%2B3%5Csqrt%7B-2%7D)
![=\sqrt{-1\times 2} +3\sqrt{-1\times2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B-1%5Ctimes%202%7D%20%2B3%5Csqrt%7B-1%5Ctimes2%7D)
The value of
.
![=\sqrt{2}i +3\sqrt{2}i](https://tex.z-dn.net/?f=%3D%5Csqrt%7B2%7Di%20%2B3%5Csqrt%7B2%7Di)
(add the coefficient of √2i, i.e. (3 + 1 = 4))
Sum of
and
is
.
Option B is the correct answer.
