Answer 2

groupings tend to be easiest when done from the inside-out

Answer 3

but it has two parentesis

Answer 4

im sure it does, care to share it?

Answer 5

if your trying to use that equation button; it might be easier just to type it outright

Answer 6

its i cant type it

Answer 7

i tried reading your mind, but all I got was boy clutter :)

Answer 8

its difficult

Answer 9

ill try and type it

Answer 10

[(1+2(3-2))+14]^2 ??

Answer 11

ok my paper is on this page just go to math-drills.com order of operations

Answer 12

then what?

Answer 13

yea its that page now go to positie and negative intigers three steps (A)

Answer 14

i meant positive

Answer 15

and which one are you stuck on?

Answer 16

number 1

Answer 17

send me an attachment to see if your in the right page

Answer 18

[ (10 div (-10) )^7 ]^2

Answer 19

yes im stuck in that one

Answer 20

its just another way to write: 1

Answer 21

but lets work thru it; what do youthink we should do first?

Answer 22

the parenteses

Answer 23

which set :)

(10 div (-10))

(...)^7

0r

(...)^2

Answer 24

the (...)^7

Answer 25

ok, but youlll prolly understand it better if we do the: (10 div (-10)) first; either way is fine tho

Answer 26

ok

Answer 27

\[(\frac{10}{-10})^7=\frac{10^7}{-10^7}=\frac{10,000,000}{-10,000,000}\]

Answer 28

im sorry but i dont get it

Answer 29

i didnt think you would for that one :) lets me guide you to an easier way

Answer 30

ok i think that (-10) goes first

Answer 31

the inner most grouping is:

(10 div(-10))

what can you tell me about this value?

Answer 32

have you done fractions yet?

\[(10\div (-10))=\frac{10}{-10}\]

Answer 33

ummm....[(10div(-10) the -10 turns into positive

Answer 34

the -10 does not turn positive; that is not in any rule of math :)

Answer 35

ohh sorry im confused

Answer 36

10 times ___ = -10 can you fill in the blank?

Answer 37

_10

Answer 38

imean -1

Answer 39

-1 is correct; which tells us that: \(10\div(-10)= -1\)

Answer 40

do i write that down in my paper

Answer 41

that is part of the process yes, there are 2 more groupings to go

Answer 42

lets go to the next in line, that ^7

Answer 43

ok

Answer 44

is this correct so far?

\[(10\div(-10))^7=(-1)^7\]

Answer 45

are the ones at the top 7 or?

Answer 46

because i wrot 7 is it ok

Answer 47

we have:

\[\left((numbers)^7\right)^2\]

Answer 48

we figured out that the "numbers" = -1 so lets move outwards to the \(()^7\) part right?

Answer 49

yes

Answer 50

imma show you what i wrote

Answer 51

(10div(-10))^7=(-1)

Answer 52

\((-1)^7\) means: -1 x -1 x -1 x -1 x -1 x -1 x -1
(-1 x -1) x (-1 x -1) x (-1 x -1) x (-1)
(1 x 1 x 1) x -1
1 x -1
-1

thats fine as long as you know that: \((-1)^7=(-1)\)

Answer 53

ok do i have my work correct

Answer 54

so far so good, just one last grouping to take care of

Answer 55

ok

Answer 56

\((-1)^2=?\)

Answer 57

is it 2

Answer 58

when we work it thru the groupings it looks like this:

\[\left((10\div(-10))^7\right)^2\]
\[\left((-1)^7\right)^2\]
\[(-1)^2\]
\[1\]

Answer 59

and no, -1 x -1 = 1, not 2 :)

Answer 60

is that the answer

Answer 61

well, it is the problem i have been working with you on hasnt it?

Answer 62
