Question

Express the following using inverse notation

1/(5x^3)

Answer 1

what do you mean by inverse notation?

Answer 2

do u mean like - 1/x = x^(-1)

Answer 3

\[y=\frac{1}{5x^3}\]
I think you mean to write this maybe
and you are looking for inverse function?

Answer 4

I have no clue what you mean really

Answer 5

The problem says "Express the following in inverse notation"

Answer 6

You can please define that for me.

Answer 7

ill take a picture of it

Answer 8

i think you are talking about multiplicative inverse? u in 6or7th grade?

Answer 9

Alright this is it

Answer 10

No Ive just been out of school for five years

Answer 11

\[\frac{1}{a}=a^{-1}\]
@imqwerty made a great guess earlier

Answer 12

oh I don't know why that is called inverse notation in your class
you are just writing the expression with negative exponents instead *

Answer 13

yea :D

Answer 14

So where is a good place to practice this because I really don't have a clue how you go the answer.

Answer 15

you see the exponent 3

Answer 16

on the bottom there?

Answer 17

yup

Answer 18

\[\frac{1}{5x^3}=\frac{1}{5} \frac{1}{x^3}=\frac{1}{5} x^{-3} \text{ use the rule I gave }\]

Answer 19

bring that little part to the numerator and change the sign of the exponent

Answer 20

That makes sense now.

Answer 21

another example:
\[\frac{5}{3(x+1)} \\ \frac{5}{3} \frac{1}{x+1}=\frac{5}{3} \frac{1}{(x+1)^1} \\ =\frac{5}{3}(x+1)^{-1}\]

Answer 22

ah I see. This was easier than what I made it seem.

Answer 23

\[\frac{ 1 }{ 5x ^{3} } = y\]
\[5y= \frac{ 1 }{ x ^{3} }\]

Answer 24

\[\sqrt[3]{5y} = x\]

Answer 25

hey is it like the minus sign of the exponent is not written or m getting something wrng.....this has happened to me before
