This is a topic that many people are looking for. thevoltreport.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, thevoltreport.com would like to introduce to you Math for fun, sqrt(3-2sqrt(2))=?. Following along are instructions in the video below:
lets do some math for fun and this times we can see we have a square root on outside and then we have 3 minus 2 and then we have another square root inside right we have this square of 2 right here and this is in fact the same as one of these and as you can see these choices right here they dont have any big square root on outside isnt it so how can that be the case right its crazy and now this is perhaps the thought process that we can you know go through right once again none of this has that big screwed on outside so what does that mean well the only way that you can cover up a square root is that you have some square and then the square root of course 10 so shut up right and whats that being said if you look at the inside this is 3 minus 2 square root of 2 maybe thats actually what secretly a perfect square we just dont know and now lets take a look alright suppose this is in fact a perfect square and this is the perfect square that we know right so I want to force it to be a perfect square so I can
show you that you know reveal the secret for you guys and think what a minus right here let me write down this for you guess we know when we have a square minus 2 a B and then plus B Square this right here its a perfect square isnt it which is going to be a minus B and a square right and with this being said can I make 3 minus 2 screw into this one because if I could do that then I can complete the square like this and then I can cancel this square and thats good run outside isnt it and now Ill be so wonderful right and now let me just write this down right here we have the street right here and then minus 2 square root 2 right and now we are just going to try to mix and match all right first of all I have this minus 2 this just mean is right here isnt it so let me put this down right here we have the minus 2 from here and we have to attach a school to after that so let me just put on a square tool right here and this guru in red it could be either the a will be right
well suppose this is for a then I will have to put a school tube right here underneath this square right so I have square root of 2 right this and then I have to square that but whats this school of 2 squared is just a regular two if you look back here this is what we have 3 well 3 is certainly too but then just have to add 1 to that right so if you look at 3s 2 plus 1 then we can make a lot of good things happen first of all this tool is right here and then this one will be going all the way to the end isnt it so let me write this down we have the plus + 4 1 let me just put it down right here and lucky D right here want the same as 1 square isnt it in your network 1 its a B for you isnt it and if you will I can go ahead and put down times 1 of course you wouldnt change anything when you multiply by 1 so as you can see a is school of to a school to be is one piece 1 and then we have this this this was interesting match still wonderful isnt
in other word this is secretly a perfect square what is it well school of 2 and then minus B which is 1 and then we have that squared thats it right so now let me do this for you guys legitimately originally you have square root of 3 minus 2 square root 2 and now you know the inside here is just that right so we have the square root on outside and then the inside is just this so Ill put this times square root of 2 minus 1 and then square right and as you can see we have the square square root they can cancel each other out be sure when you do that you do have to put on absolute value and you have to plus minus to consider and heres the deal because the inside here we have school of 2-1 guru twist bigger than what so that means this is positive that means when you can sell the square and the square root its passed deep you dont need absolute value you dont youre negative anymore so you just have four this is square root of two minus one thats it this is the result namely we will have choice B for that crazy right and hopefully you guys like this
