4/√5 steps please
-
4 / √5 = ∙ ∙ ∙ ∙ ∙ ∙ ∙ ∙ mult top/bottom by √5
4√5 / (√5 • √5) =
4√5 / 5 =
(4/5) √5
this is just rationalizing the denominator.
4√5 / (√5 • √5) =
4√5 / 5 =
(4/5) √5
this is just rationalizing the denominator.

WE never leave a radical in the denominator.
We always rationalize the denominator
4/ √5 * (√5 / √5) = 4√5 / 5
We always rationalize the denominator
4/ √5 * (√5 / √5) = 4√5 / 5

You have to rationalize the denominator.
Multiply both top and bottom of the fraction by sqrt 5.
That will give you 4 * sqrt 5 in the numerator and 5 in the denominator.
