can you help me match these/@zimmah http://scde.mrooms.org/file.php/1738/Images/5.5HW_M1P.PNG

Answer 1

it's asking for login and password

Answer 2

do u see it now i uploaded it

Answer 3

heres the answers too it

Answer 4

\[\large \sqrt[3]{64} = \sqrt[3]{2*32}=\sqrt[3]{2*2*16}=\sqrt[3]{2^6}=4\]

Answer 5

the answers do not match the questions

Answer 6

hold rite quick hold up

Answer 7

\[\sqrt{(-2)^2}=2\]

Answer 8

heres the questions

Answer 9

heres the answers

Answer 10

to solve roots, you have to break the number under the root up in prime factors

Answer 11

\[\large \sqrt[5]{-243}\]

so we have to split -243 up in prime factors.

we begin by trying to divide by 2, which won't work because it's an odd number,
so we try 3, which works, and makes 81

81 can again be divided by 3 to make 27
27 can again be divided by 3 to make 9
and 9 makes 3

so -243 = -3*3*3*3*3

Answer 12

can u match the questions with the answers like u did before because im still confused

Answer 13

\[\sqrt[5]{-3*3*3*3*3}\]

there's a 3 in there 5 times, and since it's the 5th degree root we can therefore remove 4 of the 3's and put the 5th 3 in front.

so we have \[3\sqrt[5]{-1}\]

Answer 14

still confused

Answer 15

so number 3 is question 6

Answer 16

\[\sqrt{2*2}=2 \]
\[\large \sqrt[3]{2*2*2}=2\]

Answer 17

k i have that one how about the other ones

Answer 18

the bigger the root, the more of the same number you need to 'come out' of the root

Answer 19

i am not trying to feed you answers i'm trying to make you understand how it works

Answer 20

i am

Answer 21

first you divide the big number under the root into the smallest bits you can

Answer 22

than you count how many of the same number you have, and see if you have enough of any number to break free of the root

Answer 23

if you have the 5th root, you need 5 of the same number, if you have the 3rd root, you only need 3. etc.

Answer 24

so i would do=4096/4?

Answer 25

you divide by prime numbers always

Answer 26

k so im doing it rite

Answer 27

it's best to just go through prime numbers in order, starting with the smallest.

so first 2, then 3, then 5, then 7, then 11, then 13, then 17 and you'll probably won't need any higher

Answer 28

well you can divide by 4 but that's basically dividing by 2 twice

Answer 29

so is the answer four cause i divied and got 1024

Answer 30

and then i counted

Answer 31

\[\large \sqrt[4]{-4096} = \sqrt[4]{4*1024}\]

Answer 32

oh and the - sign

Answer 33

but you can still keep dividing, it's still not in the smallest form

Answer 34

keep dividing until you can't divide any of the numbers under the root anymore

Answer 35

you can probably divide it a lot of times by 2

Answer 36

is it +13?

Answer 37

look how many times can you divide 4096 by 2?

Answer 38

2 times

Answer 39

really?

Answer 40

4

Answer 41

4096 / 2 = 2048
2048/2 = 1024

that's 2 times, but i guess we can do that about 10 more times or so

Answer 42

so its 2

Answer 43

.....

Answer 44

i'm done for today

Answer 45
