"if irrational give 2 consecutive integers which its graph lies on the number line"-->doesn't make sense

anonymous · Answer

that is what he question says

anonymous · Answer

Please check it again.  I think the word "which" doesn't make sense there

anonymous · Answer

question "determine whether $$\sqrt {67}$$ is rational or irrational. if it is irrational, find two consecutive integers between which its graph lies on a number line"

anonymous · Answer

LOL.    I hope you got the answer for first part of the question.  .  

Now tell me 2 perfect square numbers closest to 67

anonymous · Answer

64 and 81

anonymous · Answer

so its irrational?

anonymous · Answer

Take square root of both of them and they are your answer for second part of the question.

anonymous · Answer

"so its irrational? "-->obviously yes :)

anonymous · Answer

square root of 64=8 
square root of 81=9
