Thank you So much Mam.... It helped me a lot 😊Mam now I have my test on topic Herons Formula Most Popular App Unacadamy at 4.00pm By Kunal Sir..... Now three minutes left mam... Once again thank you 😊Mam

As a math teacher I can't understand why it makes sense to factor the numbers under the root??? So many steps, break down each number, write down the factors in pairs, (and if there are no pairs, what is the student supposed to do?? jump out of the window??) then eliminate one element from each pair. And finally, at the end, multiply the remaining factors, then... calculate the root!! God!!! Why??? Dear student!! Don't listen to the teacher who teaches you to do that!! no way!!! I'm amazed at the teacher who doesn't understand that the longer the road, the more errors there are! it is known. So listen to me dear student, in the end you, in any case, multiply the remaining factors and calculate the root, right?? So here is my "genius" idea: Just multiply all the numbers that were under the root in the first place!!! Why doesn't this teacher teach simple thinking??? Just make the square root of (60x35x21x4) = 420=176,400√ THANK YOU!!

Tomorrow is my exam thank you for helping 🙏 me

Thank you very much mam,i cant understood the square root step but now i can can.Once again,thank you
