Question

Hey, please help:)

Answer 1

\[3 \sqrt[3]{24}\]

Answer 2

Hint:\[\sqrt[3]{24}=\sqrt[3]{8\cdot3}=\sqrt[3]8\cdot\sqrt[3]{3}\]

Answer 3

Thank you!

Answer 4

Can you write the answer?

Answer 5

\[6\sqrt[3]{3}\]

Answer 6

Very nice.

Answer 7

Could you help me with another question?

Answer 8

\[3\sqrt{x+4}-2=13\]

Answer 9

What is the problem?

Answer 10

What cant you do?

Answer 11

Solve for \(\sqrt{x+4}\).

Answer 12

Hey! Are you here?

Answer 13

Yes, I am sorry

Answer 14

couldn't I just do 4-2 giving me 2
so then I do x+2=13?

Answer 15

x+2=13
-2 -2
x=11

Answer 16

idk

Answer 17

Can you solve \(3y-2=13\) ?

Answer 18

y=5

Answer 19

Yes. Think if \(y=\sqrt{x+4}\).

Answer 20

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?

Answer 21

square root

Answer 22

What does square root means?

Answer 23

a number multiplied by itself?

Answer 24

Can you tell me what does \(\sqrt{16}\) mean?

Answer 25

4?

Answer 26

Yes. But Also -4 too. -4*(-4)=16.
So what can you say about \(\sqrt{x+4}=5\) ?

Answer 27

x=1?

Answer 28

I don't think I know

Answer 29

See the analogy. Try to think. Compute \(\sqrt{36}, \sqrt{25}, \sqrt{\frac14}\).

Answer 30

alright. 6,5,2

Answer 31

Check the last one.

Answer 32

\(\sqrt x\) 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.

Answer 33

I still think it's1

Answer 34

Compute \(\sqrt{\frac14}\).

Answer 35

2

Answer 36

\(2^2\neq\frac14\)

Answer 37

Try again.

Answer 38

1/4

Answer 39

\(\left(\frac14\right)^2\neq\frac14\). Try again.

Answer 40

So I have to square it?

Answer 41

You have to find \(\sqrt{\frac14}\) using the definition I wrote above.

Answer 42

.5

Answer 43

.5*.5=1/4

Answer 44

Yes. Thats it. Now back to \(\sqrt{x+4}=5\). Can you solve it?

Answer 45

Would I plug something in x?

Answer 46

Ok. Can you solve this: \(\sqrt x = 2\) ?

Answer 47

4

Answer 48

Yes. Thats it. Now back to \(\sqrt{x+4}=5\). Can you solve it?

Answer 49

25?

Answer 50

\(\sqrt{25+4}\neq5\)

Answer 51

21

Answer 52

Bingo. You solved this by your own. Congratulations!

Answer 53

It has to be that's why thought of 25 =5

Answer 54

Thank you:)!!

Answer 55

You are welcome.
