1 * 1 = 1
2 * 2 = 4
3 * 3 = 9
etc....
So... 1, 4, & 9 are perfect squares
Do you understand?
OpenStudy (anonymous):
Can you show me the answer then I can figure it out thanks
OpenStudy (mathlegend):
Is 24 divisible by any of those perfect squares listed?
OpenStudy (mathlegend):
No, that is what I refuse to do. I will not just give answers. That is against the code of conduct. Anyone who does that gets reported for abuse.

Sorry I used 6 x 4

I don't believe the teacher would be looking for a decimal answer.
Crea, sqrt24 could also be written as sqrt6*sqrt4 correct?
What is sqrt4? 2.
Thus we have 2*sqrt6.
-4*2*sqrt6=-8*sqrt6.
OpenStudy (mathlegend):
Thank you.
OpenStudy (mathlegend):
So using 6 and 4 is great...
OpenStudy (mathlegend):
\[-4 * \sqrt{4*6}\]
Now, the 4 is perfect... so it comes out as what @Crea ... what is the square root of 4?
OpenStudy (anonymous):
So it's-8 square root of 6

Thank you very much

You are welcome. I all about knowing you have an understanding. That is why typing out the whole process shows just about no justice. People will learn my friend. Have a great day @Crea!
