Did you try hitting the right arrow key to "end" the square root part before hitting the 2?

Hey Kimberly Miller, hope you're having a great day! So, you want to write an answer in this form √(3) /2.

First, click on answer box, select Fraction symbol, then click on the numerator and select Square Root symbol and then type in 3 in it. Now click on denominator and type 2 in it. I think by doing this you will be able to accomplish it.

Hope this helps, let me know if it doesn't work! 

Thanks everyone for the suggestions!!. The second suggestion really helped :))

Your welcome Kimberly! ☺️ Glad I could help you out with it.
