Multiplying Radicals

Please help me understand further. I have attached a file using microsoft equation. I have try everything to include a square symbol and cube root symbol using the options here with no luck. I really need help with this problem.

Please if you know how to include these symbol in this actual text let me know so that other people can see my problem and hopefully benefit.

Thank you
