Answer:
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)
