We have to find the value of lim x-->0+
[(x^x)^2)]
lim x-->0+
[(x^x)^2)]
=> lim x-->0+ [e^(ln
((x^x)^2))]
=> lim x-->0+ [e^(ln
((x^2x))]
=> lim x-->0+ [e^(2x*ln
x)]
As the exponential function is continuous we can write
this as
=> e^[lim x-->0+ (2x*ln
x)]
As 2x*ln is of the indeterminate form we can use
l'Hopital's rule
lim x-->0+ (2x*ln
x)
=> lim x-->0+ (2*ln
x/(1/x))
=> lim x-->0+
(2*(1/x)/(-1/x^2)
=> lim x-->0+
(-2*x^2/x)
=> lim x-->0+
(-2*x)
substitute x =
0
=> 0
Now we have e^0
= 1
This gives the value of lim x-->0+
[(x^x)^2)] = 1
