Step-by-step explanation:
y=(1+2x)^1/x
logy=1/x log(1+2x)
limit on b/s ,we get
lim x tends to 0 log(1+2x)/x
multiply and divide by 2
lim x tends to zero log(1+2x)×2/ 2x
w.k.t lim x tends to zero log(1+y)/y=1
2×lim x tends to zero log(1+2x)/2x=2×1=2
lim x tends to zero log(1+2x)×1/x=2
take exponential on b/s
lim x tends to zero (1+2x)^1/x=e^2
