How many integers fall between √7 and √77 on a number line?

Where do you think \(\sqrt 7\) falls on a number line? (a rough estimate is fine)

 

Do the same thing for \(\sqrt{77}\) and count the numbers in between.

Hi, I'm not CPhill, but I'll solve it. 

 

√7 is in between integers 2 and 3, so we start from 3. 

 

√77 is in between integers 8 and 9, so thus ending with 8. 

 

3, 4, 5, 6, 7, 8

 

we have 5 integers!

 

 

Hope this helps!

oh sorry, my mistake. I think it's my estimate that is wrong. 

There are 6 numbers between 3-8 inconclusive. Bruh, my math is horrible!

 

Sorry for the confusion!

 

I need to work on my countning. LOL.

Thanks that was correct! I guess i probably could have just counted myself so no pressure!
