This guy is great! I actually understood & kind of enjoyed this!! 🤯 It was kind of funny because I got lost a little bit & he just so happened to recap right before going into the answer, brought me back on track!! Many, MANY thanks!!!

Word problem no 3 is absolutely wrong because combination of vowels is not considered please judge ur answer and dont ignore it because many jee advanced students learn this .thank you so much for ur content
Uhm does permutations mean like a group of numbers 1 3 2 if we want to find the most possible outcomes of this group do can we repeat it such as 1 2 3 and 2 3 1 etc.Thanks.
Bibi Tibi as the condition says all the vowels must be together, all 4 vowels must be considered as 1 unit as they can not be separated. On other word for each combination all the vowels are considered “1letter”. As there is no other condition remaining 7 letters are all’ considered separately. Let me know if it didn’t help, I will assist you further.
Dear Monikandan Monikandan, thank you so much for taking the time to leave this comment. I'm glad you liked it! Your feedback is always appreciated. Best regards :)
Uhm and why do you do M equals A equals 2 T equals 2 I don't get it.and does this apply to all worded problems just like this but with a different word?
permutation is when the arrangement is important and combination is when arrangement is not important. this video is helpful but go to organic chemistry's video to know what I'm talking about
The question says the vowels should always be together, so Consider vowels as one group and the other 7 consonants as 7 groups. So 7 consonants + 1 vowel = 8
@@ynnagesite5678 Because when we say vowels are always together, when there is a word together, it means one group, well logically speaking. Therefore, the vowels AAEI from the word MATHEMATICS are equal to one group. Vowels are always together = 1 And the rest which are not vowels are not equal to one group, therefore we count them. We take the vowels out which we have left with: MTHMTCS And that is equal to 7 letters. 1 vowel group + 7 letters = 8 total.
Please do not waste time by expanding factorial such as 11 or 8 etc. None of the competitive exams will be interested in solving the big factorial. Moreover the logic matters and not the expansion of factorial.
So nice of you dear! You are awesome 👍 I'm glad you liked it! Please keep sharing premath channel with your family and friends. Take care dear and stay blessed😃
