I’m 20 and I understand surds, I did A-level maths too. I just needed a video like this to figure out how to explain surds to my sister. She’s struggling with her maths. This will really help, thank you!
thank you so much ive been out of school for years cause of anxiety and im hopefully going back soon and i didnt want to be behind and for once i got it straight away
@@Cognitoedu Can you please make the practice questions and past papers on your website a lot harder, or provide harder alternatives because I find your videos packed with dense information that I find really helpful in difficult exams but the practice questions and past papers are relatively easy and I don't find them challenging. Thanks!
My teacher sucks and whenever i ask something she explains but I don’t understand shit, my blood boils working with this new woman and im not sure about this topic. Thank u this video really helped
I am a starting out maths channel and I just wanted to know what application do u use to make your videos because it looks really nice and flows well. Amazing video by the way!
Can I just ask : For all your hard work uploading these video (which are fantastic btw), do you earn anything - are these videos monetised. Just interested to see if you are being rewarded for your hard work!
Hii tysm for the video! Just a quick question, you mentioned in the video at around 4:42 that that you could still get the right answer if you pick a smaller factor but you would just need to do more steps. I was just wondering what these steps were just incase I accidentally picked a smaller factor thinking it was the biggest one and i wanted to confirm that my answer was in the simplest form.
You just have to find a square factor of the smaller number. Like for example if you did sqr(200) as 2sqr(50) you could check by finding that 25 is a factor of 50. So then you do square root 25 to get 5 and times it by 2sqr(50/25) to get 10sqr(2). Hope this helped 😁
@@thethreeadorablebears7165 ajdfuhv its literally been 3 weeks my teacher still hasnt marked it oof but last time i asked her she said she'd have it back to me by saturday and bruh that was yesterday but hopefully ill get my results by wednesday at least and then ill tell u
wait actually im wrong she said she did mark it but not the entire classes and she doesnt want to return ppls work without returning it all or sumthing
you could also rewrite the number inside the surd as a product of prime numbers and find any pair. Then for every pair you can remove the pair from the surd and have one of that number outside the surd.
@@jackzammit5792 Plenty of people type horrendously when texting, not like a YT comment section is formal or anything. Also, you forgot to capitalize your "I". If you want to judge someone at least do it correctly.
in maths the because hits different, why is 1 + 1 = 2, reason will be because 1 + 1 is 2, hahaha like ca n u explain litrally or with example, 2:29 same thing here

Thank you so much. I now understand surds after 2 years of higher maths
I was just finding the how to simplify surds and I found this video🥰. Thanks for teaching me math in this pandemic.
Waw mate this video is well explained and I am so terrible in maths do you have a video about quadratic expressions?
Thank you so much for this!! I have a test soon and this really helped me understand how to do surds!
Great to hear it helped you! Good luck with your test :)
best revision videos out of all maths vids out there. thanks :))
Thank you so much it is really helpful
YOUR THE BEST. MY NATIONAL EXAM IS NEXT WEEK 🎉😢
Thank you!
thank youu!! this helped a lot
what if i use smaller factor for a surd? my answer is different
How do I do surds when the question is for example
Square root of 48
In the form K square foot of 3
Where K is an integer
Wavey.jd15 if you know add my insta and tell me😭
Square root of 48 can be simplified to square root 16 Times Square root 3 square root 16 can simplify to 4 leaving 4 square root 3
he did 48 in the vid
@@robustsshadow why can’t it be 12 and 4 tho?
Oh wait 12 isn’t a prime number
An incredibly clear explanation so easy for students to understand. Well done.
Pov: you're watching this the night before the exam 😭
Aye g, you better than banwa g
thank you sososo much very well made video
Thank you! You won't know how tremendously your videos contribute to our GCSE studies! We really appreciate your help!
Ah thank you Viclay, glad you're finding them useful 😊
in maths the because hits different, why is 1 + 1 = 2, reason will be because 1 + 1 is 2, hahaha like ca n u explain litrally or with example, 2:29 same thing here
THANKYOU!
I get the process, but in what way is it simplified?
thank you for this video
If i use square root of 48 as 2square root 12. Is that still right?
