Problem: Find minimum?maximum for:
y=xa^(1/x)
Ans given: X=ln(a) (min)
Can't get to it.
y = xa^(1/x)
y' = (1/x) a^(1/x) (x - ln(a))
Since the first two terms are never zero, y'=0 when
x = ln(a)
y=xa^(1/x)
Ans given: X=ln(a) (min)
Can't get to it.
y' = (1/x) a^(1/x) (x - ln(a))
Since the first two terms are never zero, y'=0 when
x = ln(a)
