Maths trick by imran sir Best logic that you have ever seen Its an amazing tool to find cube of any two digit numbers with ease Very logical and easy to remember Best for all two digit numbers #imransirmaths
This is the basic formula: (a+b)³=a³+3a²b+3ab²+b³ Example: (34)³=? Just substitute a=30 and b=4 30³+3×30²×4+3×30×4²+4³= 27000+10800+1440+64=39304 No trick, just ordinary math
Sir u teach very nice and very easy thanks you sir for easly teaching us and the is also not open because of Corona that why online classes is there and thank you Soo much sir first time I see your I watch full vedio then I subscribe channel becoz I will get more knowledge for maths to do very fast and easy to understand and they have understand easly hit like here👇👇👇
Brother you are awesome in such kind of tricks but just try to take cube of number 18. You would have to make such a large additions that will take more time than its usual method. So the tricks are just for the time being and 1st the tricks we forget after some time and 2nd take more time for some other kind of questions. When we use usual or natural method to solve any multiplication then Multiplication is itself a way of preventing from more addition, but in such tricks we are involving ourselves in reciprocal process i.e making additions which definitely takes more time than a table. Thanks
Very nicely explained Thank you so much sir😇🙏🙇 To the one who still find it difficult : Keep practicing 😇it's much better(easy) than 13*13*13 (multiplying 13 three times) And note down nicely 😊just as sir did😇
I don't understand Indian language but I do understand the numbers and how he solved it. Very ingenious method of solving ❤️❤️. Can you share manual calculation of non perfect cube numbers? Since manual solving of square root of non perfect squared numbers is already available in youtube. I can't find any manual cube root of non perfect cube numbers :'(
@@mayureshmore2139 yeah i figured it out when i saw. But All those 3 method takes less time than the universal cube of 1to99 method. So i liked and learned all methods
Hahahaa. Dear this Sir is awesome in such kind of tricks but just try to take cube of number 18. You would have to make such a big amount of addition that will take more time than its usual method. So the tricks are just for the time being and 1st the tricks we forget after some time and 2nd take more time for some other kind of questions. When we use usual or natural method to solve any multiplication then As multiplication is itself a way to prevent someone from more addition, but in such tricks we are involving ourselves in reciprocal process i.e making addition which takes more time than use of a table. Thanks
Time saved if you could solve cube of 88 in less time than its usual method. First try it practically by yourself using this trick. You will become mad by doing additions. hahahaa
Not a good trick tbh; if you calculate 19^3 by this method; you'll take some more time to do the remaining calculations & in competitive exams you won't be having so much time to spent on calculations; so not a very good method
