Question

Plz help 18pts simplify 5/√10

Answer 1

Answer:

B

Step-by-step explanation:

Rationalize the denominator. That means you multiply √10 on both the numerator and denominator of the question.

$\dfrac{5}{\sqrt{10} } * \dfrac{ \sqrt{10} }{\sqrt{10} }$

The result is

$\dfrac{5 \sqrt{10} }{10}$

Notice that the 5 in the numerator, partially cancels out with the 10 in the denominator.

The answer is $\dfrac{ \sqrt{10} }{2}$

Answer 2

The square root of 10 divided by 2 is the correct answer.
