Can you write the answer?

\[6\sqrt[3]{3}\]
klimenkov
  • klimenkov
Very nice.
anonymous
  • anonymous
Could you help me with another question?
anonymous
  • anonymous
\[3\sqrt{x+4}-2=13\]
klimenkov
  • klimenkov
What is the problem?
klimenkov
  • klimenkov
What cant you do?
klimenkov
  • klimenkov
Solve for \(\sqrt{x+4}\).
klimenkov
  • klimenkov
Hey! Are you here?
anonymous
  • anonymous
Yes, I am sorry
anonymous
  • anonymous
couldn't I just do 4-2 giving me 2 so then I do x+2=13?
anonymous
  • anonymous
x+2=13 -2 -2 x=11
anonymous
  • anonymous
idk
klimenkov
  • klimenkov
Can you solve \(3y-2=13\) ?
anonymous
  • anonymous
y=5
klimenkov
  • klimenkov
Yes. Think if \(y=\sqrt{x+4}\).
klimenkov
  • klimenkov
If you make a substitution \(y=\sqrt{x+4}\), you will get \(\sqrt{x+4}=5\). Do you know what \(\sqrt{\phantom{a}}\) sign means?
anonymous

square root
klimenkov
  • klimenkov
What does square root means?
anonymous
  • anonymous
a number multiplied by itself?
klimenkov
  • klimenkov
Can you tell me what does \(\sqrt{16}\) mean?
anonymous
  • anonymous
4?
klimenkov
  • klimenkov
Yes. But Also -4 too. -4*(-4)=16. So what can you say about \(\sqrt{x+4}=5\) ?
anonymous
  • anonymous
x=1?
anonymous
  • anonymous
I don't think I know
klimenkov
  • klimenkov
See the analogy. Try to think. Compute \(\sqrt{36}, \sqrt{25}, \sqrt{\frac14}\).
anonymous
  • anonymous
alright. 6,5,2
klimenkov
  • klimenkov
Check the last one.
klimenkov
  • klimenkov
\(\sqrt x\) is the inverse function for \(x^2\). \(\sqrt x\) is a number that squared must be \(x\). \((\sqrt x )^2=x\). Think about last one.
anonymous
  • anonymous
I still think it's1
klimenkov
  • klimenkov
Compute \(\sqrt{\frac14}\).
anonymous
  • anonymous
2
klimenkov
  • klimenkov
\(2^2\neq\frac14\)
klimenkov
  • klimenkov
Try again.
anonymous
  • anonymous
1/4
klimenkov
  • klimenkov
\(\left(\frac14\right)^2\neq\frac14\). Try again.
anonymous
  • anonymous
So I have to square it?
klimenkov
  • klimenkov
You have to find \(\sqrt{\frac14}\) using the definition I wrote above.
anonymous
  • anonymous
.5
anonymous
  • anonymous
.5*.5=1/4
klimenkov
  • klimenkov
Yes. Thats it. Now back to \(\sqrt{x+4}=5\). Can you solve it?
anonymous
  • anonymous
Would I plug something in x?
klimenkov
  • klimenkov
Ok. Can you solve this: \(\sqrt x = 2\) ?
anonymous
  • anonymous
4
klimenkov
  • klimenkov
Yes. Thats it. Now back to \(\sqrt{x+4}=5\). Can you solve it?
anonymous
  • anonymous
25?
klimenkov
  • klimenkov
\(\sqrt{25+4}\neq5\)
anonymous
  • anonymous
21
klimenkov
  • klimenkov
Bingo. You solved this by your own. Congratulations!
anonymous
  • anonymous
It has to be that's why thought of 25 =5
anonymous
  • anonymous
Thank you:)!!
klimenkov
  • klimenkov
You are welcome.
