Question

Arrange the following functions in increasing order.

a)2log(n)
b)22log(n)
c)n5/2
d)2n2
e)n2log(n)

Answer 1

its Big-Oh analysis ?

Answer 2

if so-
exponential growth always overtakes polynomial or a logarithmic growth. so n^5/2 comes very last in the list.
log is the best you can have after constant. so 2log(n) comes first

could you try arranging the rest in between...

Answer 3

Had to look, apparently n^(5/2) is not a polynomial b/c fractional exponent
But it grows like a polynomial
I think the exponential you are looking for is like
2^n

Answer 4

it looked more like (n^5)/2 to me :D
even if it is a radical 5/2, it goes last. as n^2sqrt(n) grows faster than any of the listed
