Step-by-step explanation:
To evaluate the approximate square root of 7 you would take the two closest numbers which happen to be [tex]\sqrt{4}[/tex]and [tex]\sqrt{9}[/tex] so you look to see where your [tex]\sqrt{7}[/tex] falls closest which it is closer to 9.
If we simplify our [tex]\sqrt{4}[/tex] and [tex]\sqrt{9}[/tex] you would get 2 and 3
Since [tex]\sqrt{7}[/tex] is closer to the [tex]\sqrt{9}[/tex] we would say the answer is approximately 2.6 or 2.7
Hope this helps! Good luck!
