I would like to remember one fact
x^2-3*x+2=0 then x=1,2
x^2-3*x+2=0 if u take other than 1 & 2 this equation don't satisfy
ex x=3
3^2-3*3+2=0
2=0
it doesn't satisfy other than solutions for that equation
those are just eqs just like our above example
a^b=ab=ba=b^a
here I didn't...
It is easy
given a+b=ab=a^b
ans:
ab=a^b
ba=b^a
=> a^b=b^a
=> a=b ...(1)
a+b=ab
from (1)
=>b+b=b*b
=>2b=b^2
b cancel both sides
=>b=2
from (1)
a=b=2
I think I am right
