Which of the following is equivalent to

Option (2) is correct.

Step-by-step explanation:

Given expression

We have to find an equivalence value to the expression.

Radical rule,

Also,

Consider the given expression,

Applying radical rule to

Thus, the expression becomes,

Thus, option (2) is correct.

Choice B is correct.

Step-by-step explanation:

Given expression is

18-√-25

We have to simplify it.

As we know that

√-a=√-1.√a

Since we know that √-1=i

Hence,√-a=√ai

we can simplify given expression by using above equation.

18-√-25

18-√-1√25

18-i√25

18-√25i

As 25 is square of 5.

Hence ,

18-5i which is the answer.

this is a very good question
