Answer:
Option (2) is correct.
![18-\sqrt{-25}=18-5i](https://tex.z-dn.net/?f=18-%5Csqrt%7B-25%7D%3D18-5i)
Step-by-step explanation:
Given expression ![18-\sqrt{-25}](https://tex.z-dn.net/?f=18-%5Csqrt%7B-25%7D)
We have to find an equivalence value to the expression.
<u> Radical rule</u>,
Also,
Consider the given expression,
![18-\sqrt{-25}](https://tex.z-dn.net/?f=18-%5Csqrt%7B-25%7D)
Applying radical rule to
![\sqrt{-25}=\sqrt{-1}\sqrt{25}=5i](https://tex.z-dn.net/?f=%5Csqrt%7B-25%7D%3D%5Csqrt%7B-1%7D%5Csqrt%7B25%7D%3D5i)
Thus, the expression becomes,
![18-\sqrt{-25}=18-5i](https://tex.z-dn.net/?f=18-%5Csqrt%7B-25%7D%3D18-5i)
Thus, option (2) is correct.
