Hello there folks
pardon my ignorance
but i was trying to solve a simple integral
following that video on youtube
but then at the moment 3:34 he states that x/sqr(x) is equal to sqrt(x)
which i obviously believe
i typed x/sqrt(x) in wolfram alpha and it also gave me the result sqrt(x)
but i don't understand why
could any of you folks prove it to me in a (or more than one) simple explanation?
Thanks a lot!
