HELP HARD MATH QUESTION!!!!!!!!!!!!!!!!!!!!!!1

Answer 1

Nakim simplified \[3\sqrt{2X} + X \sqrt{8X} - 5 \sqrt{18} and got -10X \sqrt{2X} \] for an answer

Answer 2

Part 1: Using complete sentences, explain what Nakim did wrong.

Part 2: Show all your work to simplify the expression.

Answer 3

what is your opinion from this ?

can you solve it right here ?

Answer 4

no lol i need help :(

Answer 5

so because the first term is 3sqrt(2x) you need simplifie every terms in the same station
- so than you need to simplifie xsqrt(8x) = ? so and from -5sqrt(18) a term simplified on what you can do it

ok ?

Answer 6

so sqrt(8x) =

what is 8 using exponent,power of 2 ?

Answer 7

4?

Answer 8

this sign that 2 on exponent 4 equal 8
not is right

Answer 9

huh?

Answer 10

so if 8=2*2*2 than result that 2 on exponent ??? equal 8

Answer 11

3 :D

Answer 12

yes - so this is very easy

yes ?

Answer 13

wait can u explain step by step how to SOLVE THIS !!!!

Whats the first step and use the equation tab lol

Answer 14

than xsqrt(8x) = ?

Answer 15

yes i wann to make you solving this step by step here now

Answer 16

okay so we need simply everything

Answer 17

yes than just you need answering my questions please

ok ?

Answer 18

\[3\sqrt{2X}\] okay can we simplify that?

Answer 19

but first there is xsqrt8x =

Answer 20

we do that one next

Answer 21

yes because 3sqrt2x not can simplifie again

Answer 22

oh so that one is simplified okay so now we do \[X \sqrt{8X}\]

Answer 23

ys how can you simplifie it using this sqrt8 = sqrt(2*2*2) =

Answer 24

\[\sqrt{2 * 2 * 2 }\]

Answer 25

yes how you simplifie it ?

Answer 26

hmmm idk show me please?

Answer 27

ok

sqrt(2*2*2) = sqrt(2^2 *2) = sqrt2^2 *sqrt2
so than sqrt2^2 =

Answer 28

???

Answer 29

hmmm not surel ol

Answer 30

why how many is sqrt(x^2) = ???

Answer 31

2*2

Answer 32

what is 2*2 ?

Answer 33

idk im confused? LOL

Answer 34

so if do you know that sqrt(x^2) =x so than sqrt(2^2) = ?

Answer 35

X :D

Answer 36

right?

Answer 37

not is so if sqrt(x^2) = x so than sqrt(2^2) =2
ok ?

Answer 38

okay

Answer 39

so than sqrt(2^3) = ?

Answer 40

3?

Answer 41

when you know that sqrt(2^2)=2
and sqrt(2^3) =sqrt(2^2 *2) so than how you have got 3 ?

Answer 42

sqrt(2^3) = sqrt(2^2 *2)=sqrt(2^2) *sqrt2 =

Answer 43

there is all what you need to know

check it please

Answer 44

so what does it look like simplified?

Answer 45

so if sqrt2^2 =2 than result that sqrt(2^2 *2) = 2sqrt2

yes ?

Answer 46

so than xsqrt8x = ?

Answer 47

So it looks like this right

\[X \sqrt{8X} = 2\sqrt{2}\]

Answer 48

so and where is x ?

Answer 49

hmmm on top of the 2 on the inside right?

Answer 50

write it please !

Answer 51

\[X \sqrt{8X} = 2\sqrt{2^{^{2}}}\]

Answer 52

i meant to put X lol

Answer 53

how ?

Answer 54

whats the answer?

Answer 55

what would it look like?

Answer 56

xsqrt8x = ?

Answer 57

idk

Answer 58

xsqrt8x = xsqrtx * sqrt8 = ?

Answer 59

?

Answer 60

do you know that sqrt8 = ?

Answer 61

no

Answer 62

before you have solved it

Answer 63

im confuised

Answer 64

look it little up

Answer 65

k

Answer 66

just tell me

Answer 67

you need to learn it how you can solve it ,right ?

Answer 68

just tell me this part so we can move on

Answer 69

ok look so if sqrt8 = 2sqrt2 so than xsqrt8x = 2xsqrt(2x)
do you know how i have got it ?

Answer 70

okay so thats the simplyfy right?

Answer 71

yes but you need to continue

how is your exercise again ?

Answer 72

so the answer is \[X \sqrt{8X} = 2X \sqrt{2X}\]

Answer 73

for this midle term yes

Answer 74

okay lol and the last one to simply is

\[-5\sqrt{18X}\]

Answer 75

but in your exercise you not have wrote it hence ,check it please

Answer 76

there is -5sqrt18 right ?

Answer 77

yes

Answer 78

so than how is correct ?

Answer 79

what do u mean? thats the next part lol we have to do

Answer 80

so check it please your exercise how you have wrote firstly and how you have wrote it here little up

Answer 81

inside radical need being x or not ?

Answer 82

oh i forgot to put x at the beggind its suppose to be x

Answer 83

so than correct is -5sqrt18x

yes ,

Answer 84

so than how you can simplifie it ?

Answer 85

hmmm im not sure

Answer 86

why if do you know that 18=2*9=2*3^2
so than how will be simplified ?

Answer 87

2sqrt9

Answer 88

why ?

when sqrt9 = sqrt3^2 =3

Answer 89

hmm true so 7sqrt2

Answer 90

how you have got 7 ?

Answer 91

im not sure lol

Answer 92

so there is -5sqrt18x =

Answer 93

when sqrt18=sqrt(3^2 *2) =3sqrt2

Answer 94

hmm okay

Answer 95

so than -5sqrt18x = ?

Answer 96

-15sqrt2x

why ?

Answer 97

what does it =?

Answer 98

i wann to saying you what is the right answer for
