ANS IS B.............

STEPS
TAKE b^n common . it comes out as b.
b(1+a/b^n)^1/n

since b>a then a/b fraction. its ^nbecomes 0......... so ans is b(1+0)

that is b

@souradeep
take a^n common answer will be A....:)

though i also think it will be B

my method is

{bⁿ}(1/n)<(aⁿ+bⁿ)<{2(b)ⁿ}(1/n)

from squeeze thorem it is b

but i dnt hv answer...

got the stuff on net..

@ SHUBHODIP

B>A THEN IF YOU COMMON A^N THEN B/A IS GREATER THAN 1 THAT TO THE POWER INFINITE IS INFINITE.......
