divide:

sqrt45 / sqrt81 =

simplify:

7sqrt3 / sqrt5 =

Multiply:

sqrt7/sqrt8 X sqrt24/sqrt49 =

Thanks for the advice regarding how to show square root symbol. Also thank for taking the time to help with these problems. I have a total of 12 to do and I do not know to get started on these 3 at all. Would it be possible for someone to check the other 9 for me too please? Thank you.

7√3/√5

= 4√3/√5 * √5/√5

= 4√15/5

(√7/√8)(√24/√49)

= √7(√3/7) , because √24/√8 = √3

= √21/7
