Answer 2

Need to learn the steps properly :P

Step 2:Go to a stationery
Step 3:Buy a scientific calculator.

Answer 4

...

Answer 5

*goes to laptop scientific calculator*

Answer 6

The choices are like: \[2x^2 \sqrt{7x}\]

Answer 7

-.- Help me please.

Answer 8

\[\sqrt{(2*49)^5}\]

Answer 9

What would I do next? I don't understand .-.

Answer 10

why dont you first rewrite it like this \[\sqrt{98^4*98}\]

Answer 11

Then what would I do? I don't see what the next step would be to do.

Answer 12

what would happen if we put out the 98^4

Answer 13

Oh i see. Think of it this way:
\[98^{4/2}*\sqrt{49*2}\]

Answer 14

Divisible by 2?

Answer 15

so yeah you would actually get \[98^2*\sqrt{98}\]

Answer 16

Or simplified down more would be:
\[7*98^2 \sqrt{2}\]

Answer 17

How do you get it to 2?

Answer 18

Breaking it down.

Answer 19

Dividing 98 by 49?

Answer 20

yeah you can rewrite 98 as 49*2

Answer 21

Yup, yup

Answer 22

Oh okay. Well I have a few more questions could one of you help? They look easier than this one xD

Answer 23

And the perfect square of 49 is 7

Answer 24

Oh that's how you got 7

Answer 25

Yup :D

Answer 26

Makes more sense now :P

Answer 27

a lot more sense xDD

Answer 28

With the information I was given the answer is: \[7x^2 \sqrt{2}\] correct?

Answer 29

I wrote the first thing wrong. \[\sqrt{98x^5}\]

Answer 30

you need that to be simplified?

Answer 31

Yea thats right

Answer 32

But you're missing a piece

Answer 33

Which is?o;

Answer 34

\[\sqrt{49*2*x^4*x}\]

Answer 35

So it's \[7x^2\sqrt{2x}\]

Answer 36

There you go :)

Answer 37

Can you help me with a few more?o;

Answer 38

\[\sqrt{48}\] is my next one.

Answer 39

Well try them first then post a new question if you need help

Answer 40

Alrighty. (:

Answer 41

\[\sqrt48=\sqrt{4*4*3}\]

Answer 42

I don't know how to do them at all, that's why I asked for steps to learn :P

Answer 43

\[4 \sqrt{3}\] is that equal to \[\sqrt{4*4*3}\]

Answer 44

Yea :)

Answer 45

Can you explain why? :P

Answer 46

I'm awful at explanations.. sorry brah D:

Answer 47

How do you know it's equal to eachother then? :P

Answer 48

because \[\sqrt{4*4*3}=\sqrt{4^2*3}\] so since its 4^2 when we pull it out of the squareroot we look for \[\sqrt{4^2}=4\] so we have \[4*\sqrt{3}\] left

Answer 49

Understandable :P

Answer 50

Let me get your opinion. on this.

Answer 51

\[\sqrt{100}\] would be equal to \[50\sqrt{2}\] ?

Answer 52

not necessarily :p

Answer 53

absolutely not xD

Answer 54

Dang.-.

Answer 55

Ok so u'd find the factors of 100 which are: 10 * 10. Since it's got 2 of the same factor u can take it out of the square root
