many comments here are: "well explained" but sorry....exactly these explanations I'm missing f.e. : @4:00 the step from sqrt(18x18x35) to sqrt(90) x sqrt(126) of course I understand the reason but I think that there should be a comment of how to find these factors..... that that is a kind of repeated trying
Nice teaching
Great explanation ❤
Perfect 🥰
too good
Mast hai madam ji ❤
well done maam
Very good explanation and nice
good teacher , i saw all video and very well explained
Good going maam
Very nice 💯
Very well explained
Another shorter solution :
3√2(√7 + √5)=>3(√14+√10)
🙏🏿
From
√(36*(6+√35))/(6^2-(√35)^2))
=√(36*(6+√35)/(36-35))
=√36*(6+√35) =6√(6+√35)
=6√(1/2*(12+2*√35)) [Note that √(1/2)=√2/2]
=6*√2/2*√(7+5+2*√7*√5)
=3√2*√((√7+√5)^2)
=3√2(√7+√5)
=3((√2*√7)+(√2*√5))
=3(√14+√10)
👍🏾
6 -root35 = 2(root7 - root5)^2

Sqrt[36/(6-Sqrt[35])]=3Sqrt[14]+3Sqrt[10] It’s in my head.
از همان ایتدا میتوانستی بوسیله فرمول رادیکال مرکب این دو رادیکال مجزا را استخراج کنی بانو❤❤❤😊😊
18+18=36 your answer is going wronģ
