About Ritam
I am guest lecturer at Sur Tech college Dumdum (JIS University) , I want to share my knowledge with you students as many times I have seen students are capable to learn but they are just get bored with old lengthy techniques and feel they are not capable of solving maths problems. I think we will be able to solve it togather.

You all know number tables but have you tried like this?
2×2=4
4×2=8
8×2=16
16×2=32
32×2=64
And so on . In this way it will be easy to find any power of a number.
Let's see another, suppose you have to make a password with 5 character two of them should be letters and others are digit,the first character is always a digit but not zero how many such passwords possible?
Think how many digits are there in between 0-9 ?
10 digits, now if first character is not 0 then choices are 9 and for letters we have 26 choices
So number of password we can make are 9×26×26×10×10
