I believe one of the answers is D, but i cant find any other ones. Can someone check my work and make sure i am correct? thank you!

sqrt(15)/ sqrt(3)

sqrt(5)

sqrt(25)/ sqrt(5)

Step-by-step explanation:

Sqrt(100)/sqrt(20)

We know sqrt(a)/sqrt(b) = sqrt(a/b)

Sqrt(100/20)

sqrt(5)

sqrt(100)/sqrt(20)

10 / sqrt(4) sqrt(5)

10/2 sqrt(5)

5/ sqrt(5)

Rewriting 5 as sqrt(25)

sqrt(25)/ sqrt(5)

We can also look at

sqrt(15)/ sqrt(3)

We know sqrt(a)/sqrt(b) = sqrt(a/b)

sqrt(15/3)

sqrt(5)

There are 3 choices that are equal to sqrt(100)/ sqrt(20)
