your answer
given :-
8×2^n+2=32
now we know 8=2^3
32 =2^5
so
2^3×2^n+2=2^5
now when same number are multiplied with different powers the power get added for example 1^1×1^1=1^1+1=1^2
so
2^n+2+3=2^5
2^n+5=2^5
[2 gets cancelled from both sides ]
n+5=5
n=0
hope helps

can't understand
look when same numbers have different powers we add the powers
ok
^ sign means power of that number
i know
but it will be 2^n+2=32-8
no no we will have to change it in form of 2
your dob is 2200
