Answer :
Final answer:
The equivalent expression for √-18 is 3i√2. This can be found by recognizing that the square root of a negative number involves the imaginary unit i, where i^2 = -1. Therefore correct option is E
Explanation:
The question is asking for the equivalent expression for √-18. The square root of a negative number involves a complex number, specifically i, where i is the imaginary unit with the property that i^2 = -1.
Therefore, √-18 can be rewritten as √(-1*18), which is √-1 * √18.
This simplifies to i * √18.
We further simplify √18 to 3√2, so that the expression becomes 3i√2, which is not presented in the choices given. However, if there is a typo in the choice e. 3√/2i and it is meant to be 3i√2, then that would be the correct answer.
