explain @MATTW20

- anonymous

if you have an expression with a negative exponent that is in the bottom portion of the fraction. putting it in the top of the fraction makes it positive.

Choose the correct simplification of the expression (2b over c)^3.
2b^3 over c^3

both expressions get raised to the third power because they're in parentheses

b. When you have variables with exponents over variables with exponents you subtract the exponents

@MATTW20 last one i promise !
Show the expanded form and simplification of x^6 over x^2. Explain in your own words how you can simplify x^6 over x^2 without having to write the expanded form.
Create your own fraction with like bases, coefficients, and show its simplification

|dw:1362510116798:dw|

- anonymous

you can simplify (x^6)/(x^2) without writing expanded form by using the formula \[\frac{ x ^{a} }{ x ^{b} }=x ^{a-b}\]
so \[\frac{ x ^{6} }{ x ^{2} }=x ^{6-2}=x ^{4}\]

thank u !!!!!

- anonymous

As for the last one all you have to do is make up a problem of your own and solve it

- anonymous

thats the part im not good at

- anonymous

why?

- anonymous

you can make it as easy or difficult as you like

- anonymous

yeaa but i have no clue aout this. so i would know how to even make an equation or solve it :/

- anonymous

just put some in the form of \[\frac{ x ^{a} }{ x ^{b} }\] a and b can be whatever number you like

- anonymous

just make them different numbers

@mikaa_toxica13

- anonymous

sory. i was preoccupied. u know with what lol. something like x^5 over x^7 ?

- anonymous

@MATTW20

- anonymous

okay so now you use the formula i showed you earlier \[\frac{ x ^{a} }{ x ^{b} }=x ^{a-b}\] just substitute a for 5 and b for 7

- anonymous

so it would be
x^5
--- = x^5-7
x^7

- anonymous

which is \[x ^{-2}\]

- anonymous

but what if we wanted the exponent to be positive?

- anonymous

oh i thought it was supposed to be like 5 minus 7

- anonymous

well what is 5-7?

- anonymous

idk btw the second answer u gave me was wrong.

- anonymous

sorry about that It's been a while since taking algebra. The answer is right but idk what you're instructor was looking for in the explanation.

- anonymous

anyway the answer would be \[x ^{-2}\] or if you like \[\frac{ 1 }{ x ^{2} }\]

- anonymous

oh the 2nd overall answer. My fault i completely apologize. It would've been b.

- anonymous

anyway good luck sorry about the mistake. I'm here to help if you need it

- anonymous

i got it thanks maybe u should recheck your math

- anonymous

yes ma'am
