Question

i got three questions and that's it .

simplification of the expression 4 over y exponent -3

Answer 1

please help !

Answer 2

\[\LARGE \left(\frac 4y\right)^{-3}\] this ? :)

Answer 3

yes except the -3 is with the y ,

Answer 4

its 4 over y ^-3

Answer 5

Got it :) ...

Answer 6

\[\LARGE \frac{4}{y^{-3}}=\cfrac{4}{\frac{1}{y^3}}=\cfrac{\cfrac41}{\cfrac{1}{y^3}}=\frac{4\cdot y^3}{1\cdot 1}=4y^3\]

Answer 7

do you understand it ? :)

Answer 8

next questions remember i need help with three questions

Choose the correct simplification of the expression a^6b^3 over a^4b^2


i got choices

A. A^2 / B

B.A^10B^5

C.A^10/B^5

D.A^2B

Answer 9

Find the attached image..You might understand it

Answer 10

\[\LARGE \frac{a^6b^3}{a^4b^2}\]

use this rule:
\[\LARGE \frac{x^a}{x^b}=x^{a-b}\] can you do it ? :)

Answer 11

let me try . :)

Answer 12

ok

Answer 13

what would be x ?

Answer 14

\[\huge \frac{a^6b^3}{a^4b^2}=a^{6-4}b^{?-?}\] try this :)

Answer 15

i got choice b

Answer 16

No. that's wrong. Eliminate choice B , you have 3 choices remaining...

Answer 17

okay . hmmm your a good teacher

because you have 6-4 , and that leaves 2 , then 3-2 =1 leave the variable b by its self

Answer 23

... 100% true.. @Rudi19 Thank you. ;)

Answer 24

@janayx3 Can you solve this? :)
\[\LARGE \frac{x^5y^3}{xy^2}\]

\[\LARGE A) x^4y^2\]
\[\LARGE B) x^4y\]
\[\LARGE C) x^3y^2\]

Answer 25

It's Option B... I have to go. Good Night. :)

Answer 26

goodnight :\
