lol, theres no way someone spent 15 HOURS on something that can be done in 15 minutes... an hour or 2 at most

May I just say you're honestly the best math teacher I have ever had. You're explanations make it so easy to comprehend . Thank you for your time and work.❤🎉😊

I have my final non-calc gcse exam today. This channel has genuinely helped so much this year. I was failing my sciences and maths before 2021. I had more mocks a few months ago: purely due to how helpful this channel is, i've improved by as much as 4 grades higher in chemistry. Originally getting a 4, then in my most recent mocks, getting almost a 9. Thank you :)

[@Cognitoedu]

Wow Lucie that's amazing, you've improved so much!! we hope your exams go well today, so glad we could help 😊

In that last example, where he simplified the square root of 48 as 4√3 why was it then not broken down again to read 2√3 (as the square root of 4 is 2). I’m confused..

[@dewimoore7413]

Because its just 4√3 if it was √4 then you would simplify it to 2

[@Hambo04]

@@dewimoore7413 Thanks for clearing that up, much appreciated.

[@niktambar5324]

what two numbers multiply to give you 75? (it's better to use square numbers ) so 3 * 25 = 75. so, √3 * √25 = 5√3. now there is a 2 outside the 75 right? so all we do is multiply the 2 with the simplified surd! so 2 * 5√3 which gives us 10√3 . hope you understood!

[@aktarrahman3560]

What about when we are using other factors, like 4×12, then the square root of 4 is 2, then it's 2√12, right? How is it solved in that case?

[@LilShakkas]

Best video, just a question. In the last example why is 2 root 75 simplified as 10 root 3? I got 2 root 25 x 3 which totaled 7 root 3 due to root 25 being 5? I'm lost

[@niktambar5324]
