Question

(x2y)3

Answer 1

Please include the instructions that came with the math problem.

Answer 2

no question. just products and factoring

Answer 3

You're supposed to do something with the expression you typed in. What?

Answer 4

(x^2y)^3

Answer 5

That's a lot clearer, by the way, and I was going to ask you to write it in that manner. But what's your goal in posting this expression?

Answer 6

Got you.

Answer 7

Got me in what sense? Know what to do with this expression next?

Answer 8

No not really don't kow what to start with

Answer 9

\[(x^2y)^3\] was typed with Equation Editor.

Rule of exponents:

\[(x^a)^b=x^{ab}\]

Answer 10

Thats where i got lost at

Answer 11

Look at this rule: Inside parentheses we have x raised to the power a. We raise that whole expression to the power b. The result, according to this rule, is x^(ab). (Multiply together exponents a and b.)

Answer 12

Good to write this and other rules down for later reference and review. You'll need them later.

Answer 13

Here's another example of rules of exponents:\[x ^{a}x ^{b}=x ^{a+b}\]

Answer 14

Don't just want to continue throwing rules at you, but we do need to know such rules in algebra. So: what could I do for you next?

Answer 15

so the answer would be xy^6

Answer 16

I'd prefer not to talk in terms of "answers." Mind showing me how you obtained that result?

Answer 17

(x^2y)^3 = ? Which of the two rules I gave you applies here?

Answer 18

the way you said multiply the exponents. did that.

Answer 19

(x^2y)^3 looks like \[(x ^{a}y ^{b})^{c}\] Can you agree with that?

Answer 20

thats more like it

Answer 21

Yes, and \[(x ^{a}y ^{b})^{c}\] is equivalent to\[x ^{ac}y ^{bc}\]

Answer 22

So, your (x^2y)^3 would equal what?

Answer 23

well im half right. what i did was add the exponents x^5y^8

Answer 24

(x^2y)^3 could be re-written as (x^2y^1)^3, or \[(x^2y^1)^3\]

Answer 25

First, please multiply that power " 2 " by 3. Next, mult. that power 1 by 3. What do you get as a result?

Answer 26

\[x ^{?}y^?\]
