Question

(2+3SQ) (3-3SQ)

Answer 1

What does "3SQ" mean?

Answer 2

Is it???\[(2 + 3^{2})(3 - 3^{2})\]

Answer 3

YES

Answer 4

So how much is 3^2 (3 squared)?

Answer 5

Do u know that 3^2 = 3 * 3 (three threes)?

Answer 6

NO IM LOST

Answer 7

I just want to know your level, do you know what

three times three is?

Answer 8

Um, do u know your multiplication tables?

Answer 9

??

Answer 10

NO

Answer 11

YEA LOL

Answer 12

So u use a calculator?

Answer 13

Little joke, eh? :-)

Answer 14

I DONT KNOW HOW TO DO THE ONE ON TOP

Answer 15

Still, I would like to what 3 times 3 is?

Answer 16

9

Answer 17

OK, when you multiply a number by itself, you say u are "squaring" the number and write it as 3^2 (if u are typing it) or

\[3^2\] if you use the equation editor.

Answer 18

CAN YOU SHOW ME THE DIFF WAS TO WRIGHT 3.3 LIKE UMMM IT LOOK THIK A / SINE

Answer 19

Don't use CAPS, its the same as shouting...

Are u asking whether u can write 3*3 as 3.3?

Answer 20

NO LIKE SQ SINE

Answer 21

\[x^2\]

The little 2 means "squared".

Answer 22

YEA AND THE ONE THAT LOOK A /

Answer 23

If u mean like 1/2, the / means "divide by"

Answer 24

no and sry for us cads . idk how to wright it there no key on my key bord 4 it .. thanks anyway

Answer 25

It is usually above one of the numbers (on mine, it is above the 7 at the top of the keyboard).

Answer 26

U are talking about / , right?

Answer 27

it look like a 7 sideways onlyway i can tell u waht it look like

Answer 28

^

Answer 29

That one?

Answer 30

Answer 31

>

Answer 32

Copy it from somewhere and paste it so I can see...

Answer 33

??

Answer 34

im try

Answer 35

OK.

Answer 36

\[\sqrt{?}\]

Answer 37

OK, that is the opposite of "squaring".

It means to take the "square root" of something.

eg \[\sqrt{9}= 3\] and \[3^2 =9\]

Answer 38

so it mean sq

Answer 39

No, it mean "square root".

You can type sqrt eg sqrt(9) = 3

Answer 40

3 times 3 is 9

9 is the "square" of 3

3 is the "square root" of 9.

Answer 41

so (2+\[\sqrt{3}\]-4 \[\sqrt{x 3}\]+3x\[\sqrt{72}\] whhen x =2 what is this

Answer 42

thanks so much your awesome

Answer 43

3x the 1st part not 2+ sryb

Answer 44

\[3x+\sqrt{3} -4 \sqrt{x3} +3x\sqrt{72}\]

When x is 2?

Answer 45

3x+\sqrt{3} -4 \sqrt{x3} +3x\sqrt{72}

Answer 46

\[3x \sqrt{8}\] -4 and everything els right

Answer 47

\[3x\sqrt{8} -4 \sqrt{x3} +3x\sqrt{72}\]

Answer 48

3x\sqrt{8} -4 \sqrt{x3} +3x\sqrt{72}

Answer 49

If you paste the above in equation editor, u can alter it...

Answer 50

put a x after the 8

Answer 51

\[3x\sqrt{8x} -4 \sqrt{x3} +3x\sqrt{72}\]

Answer 52

yea when x is 2

Answer 53

Is it x3 or 3x? (in the middle).

Answer 54

x3 and the 3 is little

Answer 55

\[3x\sqrt{8x} -4 \sqrt{x^3} +3x\sqrt{72}\]

Answer 56

Correct now?

Answer 57

yea

Answer 58

3x\sqrt{8x} -4 \sqrt{x^3} +3x\sqrt{72}

Answer 59

Please copy above, then press "equation" button below and paste it in...

Answer 60

Then press "Insert"

Answer 61

Then press "Post"

Answer 62

Can u do that?

Answer 63

3x\sqrt{8x} -4 \sqrt{x^3} +3x\sqrt{72}

Answer 64

like that

Answer 65

You have to press "Equation" button (the one on the left) and paste it in there....

Then in the same place, u see a button "Insert", press that.

Finally, press the "Post" button.

Answer 66

Nothing happened

Answer 67

U were not able to paste?

Answer 68

After I pasted it in th box after click Equation, I pressed insert and then post and nothing happened.

Answer 69

After u paste, did u see the equation appear in the box?

Answer 70

\[3x\sqrt{8x} -4 \sqrt{x^3} +3x\sqrt{72}\]

Answer 71

Yes! Well done.

Answer 72

there got it. There was a space infront of the three.

Answer 73

So you should keep a copy of this somewhere so u can play later...

3x\sqrt{8x} -4 \sqrt{x^3} +3x\sqrt{72}

Answer 74

Now back to your questions, do you want to do your first question or the second one?

Answer 75

2nd one

Answer 76

3x\sqrt{8x} -4 \sqrt{x^3} +3x\sqrt{72} when x is 2 is:

3*2 sqrt(8*2) -4 sqrt(2^3) + 3*2 sqrt(72)

Ok so far?

Answer 77

yea

Answer 78

Do you know what 2^3 means?

Answer 79

2^2 means 2*2, 2^3 means 2*2*2, 2^4 means 2*2*2*2, get it?

Answer 80

got it thanks

Answer 81

So now we can write 3*2 sqrt(8*2) -4 sqrt(2^3) + 3*2 sqrt(72) as

6 sqrt 16 -4 sqrt 8 + 6 sqrt 72

Yes?

Answer 82

72 has a x too sry ..but im wit you

Answer 83

OK,

6 sqrt 16 -4 sqrt 8 + 6 sqrt 144

Answer 84

Yes?

Answer 85

got it

Answer 86

Now 4 times 4 is 16 so 4 is the "square root" of 16, agree?

Answer 87

ok

Answer 88

And 12 times 12 is 144, so 12 is the square root of 144, Ok?

Answer 89

ok

Answer 90

So now we write 6 sqrt 16 -4 sqrt 8 + 6 sqrt 144 as

6*4 -4 sqrt 8 + 6*12 = 24 -4 sqrt 8 +72 = 96 - 4 sqrt 8

Agree?

Answer 91

ummmm yea

Answer 92

U lost?

Answer 93

yea

Answer 94

Where?

Answer 95

i got it now. go on

Answer 96

OK, now we have a bit that is trickier, the sqrt(8)...

Answer 97

We want a number multiplied by itself that is 8 and there isn't an "easy" number like before, is there?

Answer 98

no
