look 1 we have to take hcf which is8 i no this only bro
ok the brief description is that your room area is 40×48 m² if you need a square then it's largest length should be equal to 40 because if u take greater then 40 then it's width is greater then room's width so u have to take it 40×40 for a clearance ...
ok
then
what is the answer it is more then 1 hour
it's should be 1600
no
it is 8 by the way thanks

ya we have to take hcf

2^(m+n)÷2^(m-n)=16
2^(m+n)×2^-(m-n)=16
2^m+n-m+n =16
2^2n=16
2^2n=2⁴
so..base is equal then comparing powers
2n=4
n=2
putting the value of n in above ...get the value of m similarly...
3^p÷3^n=81
3^(p-n)=3⁴
P-N=4
now from the above n=2
p=4+2=6
2^(m+n)×2^-(m-n)=16
2^m+n-m+n =16
2^2n=16
2^2n=2⁴
