There is two errors in 3rd step 1st is that 2¹ is 2 not 1 and 2nd one is 2⁰ is 1 not 0

It's totally wrong that you have done in the 3rd step. You wrote 2¹=2 not 1 and 2⁰=1 not 0.!!!!

Kaha se aate hain ye log matlab kuchh bhi, kaise bhi karke prove kr dena hai, ye doubtnut sahi name hai, doubt ko clear karne ke liye nhi doubt ko badhane ke liye

sir you are teaching wrong 2⁰=0, 2¹=1, this is wrong .right is 2⁰=1, 2¹=2

You took 2^n common then how again came 2^0+2-^1 it would have been 1 + 1^-1 since you took 2^n common

How there is two inside if we take it common and (3/2)/2=3/4

You are very chaupat teacher 😂 because you written 2^1 = 1 but actually 2^1 = 2
