फैक्टोरियल (Factorial)| कितने 0 होंगें, 2 की कितनी घात होंगी | For All Competitive Exam | Brahmastra

🎓 Hello friends! I am Mahadeo Bhopte and welcome to the Teach Tech Classes channel. Here we teach Mathematics (Hindi/English medium) in simple ways for preparation of competitive exams like Banking Clerk/PO, Railway, SSC-CGL/CHSL, CAT, MAT etc. 📌 In this short video: “Factorial | How many 0s will there be & what will be the power of 2 | For All Competitive Exams | Brahmastra Series” In this, we will learn: 1. When asked ‘n!’ (n factorial) – how to find its **trailing zeros (“how many 0s” will there be in the remaining letters)**. 2. Also – “What will be the power of 2 (highest power of 2) in factorial” – this question also comes up frequently in competitive exams (Quantitative Aptitude). 3. We'll cover both topics with easy tricks and practice MCQs—to help with both board and competitive exam preparation. 🧠 In this video, you'll learn: • n! = 1 × 2 × 3 × … × n — what it means and why it's important to understand. • Formula for finding trailing zeros:   ⌊n/5⌋ + ⌊n/5²⌋ + ⌊n/5³⌋ + … = zeros in n! • Method for finding powers of 2: ⌊n/2⌋ + ⌊n/2²⌋ + ⌊n/2³⌋ + … — why it's asked in competitive exams. • We'll solve some MCQ examples—so you can practice right away. • Tips: How to save time and reduce mistakes—especially when the paper is under pressure. 📚 For further preparation: • Check out the “Number System – Brahmastra Series”, “Maths Tricks for Competitive Exams”, “Speed ​​Maths Series” playlists on our channel. • Practice these tricks for 5-10 minutes every day—this will improve your mental speed and give you confidence on exam day. • Comment below the video: What topic do you want next?
