Yes

Hey dude, I'm off of adding and subtracting polynomials and now I'm multiplying and dividing.. just need help on a few of them, not as many as last time

OpenStudy (broskishelleh):

Ok then, I just did this a couple weeks ago I'm ready

Choose the correct simplification of the expression (x^2y)^2. x^4y^3 x^6y^6 x^4y^2 xy^4

OpenStudy (broskishelleh):

C x^4y^2

OpenStudy (anonymous):

Thought so, but then I thought NO, ITS TOO OBVIOUS!!! O.O lol

OpenStudy (anonymous):

Compare and Contrast: Below are two expressions. Simplify each and then choose the statement that is true. (3d)^3(d) & (3d^2)^2

OpenStudy (anonymous):

The exponents in Expression #1 are greater than the exponents of Expression #2. The exponents on Expression #2 are greater than the exponents of Expression #1. The exponents of Expression #1 are the same as the exponents of Expression #2. The relationship cannot be determined with the given information.

OpenStudy (broskishelleh):

(3d)^3(d): 27d^4 (3d^2)^2: 9d^4

OpenStudy (broskishelleh):

It is C

OpenStudy (anonymous):

Thanks! :) just 2 more please?

OpenStudy (broskishelleh):

Ok

OpenStudy (anonymous):

Choose the correct simplification of the expression (3x)^4. 81x^4 12x^5 81x^5 12x^4

OpenStudy (anonymous):

I believe it's D

OpenStudy (broskishelleh):

It is actually A

OpenStudy (anonymous):

Can you explain why? :/

OpenStudy (broskishelleh):

Okay, see you have an exponent of 4 on the outside. Now what is 3 x 3 x 3 x 3, it is 9 x 9 right

OpenStudy (anonymous):

Right

OpenStudy (broskishelleh):

Now that four goes for both numbers, so basically you have 81^4

OpenStudy (anonymous):

ohh okay

OpenStudy (anonymous):

last one, ill put it in a new question

OpenStudy (broskishelleh):
