Hey Aqsa!

I jotted down some notes for you to look at, which are below. Be sure to also check out the available videos, articles, and exercises too!

Note that once the square roots are taken above, the result is a whole number, and that whole number will be multiplied by the one next to it (recall that when values are next to each other, they are being multiplied).

Hopefully, this helps you better understand the questions and what they aim to teach you. Feel free to let me know if you have any further questions!
