Answer:
Option B is the smallest number.
Step-by-step explanation:
We can understand which one is the least / smallest number by estimating their value.
For A we know that [tex]\sqrt{17}[/tex] is larger than 4 but is smaller than 5 because
[tex]\sqrt{16} = 4[/tex]
[tex]\sqrt{25} = 5[/tex]
Therefore since [tex]\sqrt{17}[/tex] is between [tex]\sqrt{16}[/tex] and [tex]\sqrt{15}[/tex] is larger than 4 but smaller than 5.
Option B = 4
For C we know that the value will be more the 4 because the numerator is larger than 8 since [tex]\sqrt{80}[/tex] is larger then [tex]\sqrt{64}[/tex] (which equals to 8).
From all of this information, we can conclude that Option B is the smallest number.
