Question

I need help !!!!FRANTIC!!!!

Answer 1

which one?

Answer 2

mainly all of them but to start off the first 1

Answer 3

k
find a perfect square inside the radical and pull it out like this
\[\sqrt{32}=\sqrt{16\times 2}=\sqrt{16}\sqrt2=4\sqrt2\]
you do those steps in your head, i only wrote it out like that so you could see what i was thinking

Answer 4

that makes
\[4\sqrt{32}=4\times 4\sqrt2=16\sqrt2\]
repeat the process for \(6\sqrt{50}\)

Answer 5

let me know what you get
once you do that we will combine like terms

Answer 6

42

Answer 7

forty two?

Answer 8

what did you get for \(6\sqrt{50}\) ?

Answer 9

6 square root of 50 is 42.42

Answer 10

ok i think you are not getting what you are supposed to do
there are no decimals approximations or calculators involved here
you answer needs to look like some number times \(\sqrt2\)

Answer 11

the idea is to write each number in simplest radical form
do you see how i turned
\(4\sqrt{32}\) in to \(16\sqrt2\) ?

Answer 12

yes looks like you half 32 and 4 and flipped t

Answer 13

\[3\sqrt{25}\]

Answer 14

or flip it is that rght

Answer 15

not quite
i did not take half of 32

Answer 16

im just confused on how to work square roots

Answer 17

the reason for the 16 out front was not that i took half of 32

Answer 18

k let me ask a simpler question
what is \(\sqrt{16}\) ?

Answer 19

4

Answer 20

right

Answer 21

that makes \[\sqrt{16}\sqrt{2}=4\sqrt{2}\]

Answer 22

now what is \(\sqrt{25}\) ?

Answer 23

5

Answer 24

k good
what makes
\[\sqrt{50}=\sqrt{25}\sqrt{2}=5\sqrt2\]

Answer 25

i meant "that makes"

Answer 26

so 5 of a square root

Answer 27

right

Answer 28

so its 5

Answer 29

in total you have
\[4\times 4\sqrt2+6\times 5\sqrt2=16\sqrt2+30\sqrt2\]

Answer 30

so to finish, since they already put the \(\sqrt2\) in the problem all you have left to do is add \(16+30\)

Answer 31

thank you so so so much @satellite73

Answer 32

yw
want to do the next one too?

Answer 33

yes if you have time and dont mind

Answer 34

sure
this time we go quicker
\[50\times 22=1100=11\times 100\]

Answer 35

and \[\sqrt{11\times 100}=\sqrt{11}\sqrt{100}=10\sqrt{11}\]

Answer 36

you get \[3\times 10\times \sqrt{11}=30\sqrt{11}\]

Answer 37

more or less clear?

Answer 38

Clear

Answer 39

k
the last one is real easy because there is only one answer that makes sense

Answer 40

\(\sqrt{y^2}=y\) so pick the only answer with a \(y\) outside the radical and no \(y\) inside the radical

Answer 41

I would like to give you your ribbons but only able to give you one

Answer 42

lol thanks, but i have plenty
i can't redeem them for valuable prizes, but i appreciate the thanks

Answer 43

Youre an awesome help

Answer 44

ty

Answer 45

so im suppose to multiply right 3 and 2 which would be 6

Answer 46

which problem you talking about?

Answer 47

Last one

Answer 48

oh no careful

Answer 49

you do not multiply anything
certainly not the exponents
lets go slow

Answer 50

ignoring every part but this \(\sqrt{y^2}\) it should be clear that \(\sqrt{y^2}=y\)

Answer 51

like for example \(\sqrt{5^2}=5\)

Answer 52

oh so what you said before about it staying on the outside its 2y

Answer 53

yeah , the \(y\) comes outside the radical

Answer 54

\[\sqrt{\text{stuff }y^2}=y\sqrt{\text{stuff}}\]

Answer 55

so i would actually get \[9xy \sqrt{2y}\]

Answer 56

so pick the only answer without a \(y\) inside the radical
no
pick the one with NO \(y\) inside

Answer 57

i.e. the last option

Answer 58

oh i see why thank you
