Question

Simplify the following expression, and rewrite it in an equivalent form with positive exponents.
-30x^4y^-4/120x^-2y^-4

Answer 1

This is what I got for an answer let me know if I am right (-30/120) * (x^4y^-4/x^2y^-4)

-4y/x^2

Answer 2

jhonyy is that right so far or is it wrong

Answer 3

is wrong

Answer 4

okay

Answer 5

so -30/120 =

Answer 6

.4

Answer 7

in farction form

Answer 8

fraction

Answer 9

i like yoi learn it

Answer 10

you

Answer 11

camon

Answer 12

in fraction form is 2/5

Answer 13

why ?

Answer 14

2 divides into 5 .4 times

Answer 15

-30/(4*30)

Answer 16

-225 is the answer for that

Answer 17

no than will be -1/4

Answer 18

how?

Answer 19

so x4/x(-4) = x(4-(-4))

Answer 20

how ? because 120=4*30

Answer 21

30 simplify by 30 and will remain -1/4

Answer 22

okay

Answer 23

do you understand now sure ?

Answer 24

yes

Answer 25

ok so there is x4/x(-2) than will be x on (4-(-2)) = x on 4+2 = x6

Answer 26

yes ?

Answer 27

yes

Answer 28

so y(-4)/y(-4) = ?

Answer 29

a/a = ?

Answer 30

camon

Answer 31

easy

Answer 32

y^16

Answer 33

no

Answer 34

y^8

Answer 35

a/a = ?

Answer 36

a^2

Answer 37

a divide a

Answer 38

=1

Answer 39

yes

Answer 40

y^-4/y^-4 = y

Answer 41

because y(-4)/y(-4) =1
because are the same terms

Answer 42

is 1

Answer 43

right

Answer 44

understandably now ?

Answer 45

yes but what is my final answer gonna be 1/4x^6/y or turn it around?

Answer 46

-x6/4

Answer 47

okay so I am not gonna have the y in there right?

Answer 48

yes your answer without y

Answer 49

but with minus

Answer 50

okay now I understand

Answer 51

(-1/4)(x6) or (-x6)/4

Answer 52

understandably sure ?

Answer 53

yep understanbly

Answer 54

do you have again ?

Answer 55

anything

Answer 56

nope I have a different question now to ask

Answer 57

Simplify the following expression
\[\sqrt{-121} \sqrt{-24}\]

Answer 58

121=11*11
-1=i*i
24=6*4

Answer 59

minus * minus = ???

Answer 60

okay thought that was right but wasn't sure if it had the "i" in it or not

Answer 61

positive

Answer 62

yes than result that in your answer not will exist i

Answer 63

okay

Answer 64

than sqrt(-121*(-24))= ?

Answer 65

one sec

Answer 66

53.9

Answer 67

why ? how you have got it ?

Answer 68

make the calcule here

Answer 69

well sqrt -121 is 11 and sqrt of -24 is 4.89 rounded up will be 4.9 so times 11*4.9 and get 53.9

Answer 70

no

Answer 71

okay

Answer 72

there is sqrt(-121)*sqrt(-24)=sqrt(-121*(-24))=sqrt(121*24)=sqrt(11*11*4*6)
=11*2sqrt6=22sqrt6

Answer 73

how do you get a sqrt of 6 ?

Answer 74

24=6*4

Answer 75

sqrt24=sqrt(6*2*2)=2sqrt6

Answer 76

sqrt of 6 is 2

Answer 77

no sqrt of 4 = sqrt 2*2 =2

Answer 78

okay your right

Answer 79

now all is understandably ?

Answer 80

yes

Answer 81

have you again ?

Answer 82

no that is the last problem

Answer 83

ok bye

Answer 84

Andrew from Hungary

Answer 85

Answer 86

And Thank you it was also nice meeting you

Answer 87

nice to meet you

Answer 88

good luck

Answer 89

you too

Answer 90

bye

Answer 91

bye

Answer 92

Start with the inner expression, -30x^4, and work outwards.

( ( ( (-30x^4 )y^-4 )/120 )x^-2 )y^-4 =\[-\frac{30 x^4}{\left(\left(y^4 120\right) x^2\right) y^4}= \]\[-\frac{x^2}{4 y^8} \]
