Question

Select all of the terms that are "like."

xy^2
2xy
x^2
-xy
2x^2y
1/2xy

Answer 1

Are all of the multiple choice together or separated?

Answer 2

i think its together

Answer 3

Let me fix that

Answer 4

replace the variables with actual numbers

Answer 5

xy^2

2xy

x^2

-xy

2x^2y

1/2xy

Answer 6

All the ones that have the same "base" are similar,

eg. ab, 3ab, -2ab are all like terms, base is ab.

ab, ab^2, a^2b, 1/(ab) are not; different bases.

Answer 7

So if the a and the b are together then they are similar. But if the are separated like a^2b then they are different?

Answer 8

if you repace the variables and but 2=y and 2=x you get two answers that are the same but if you put 4=y and 5=x you dont
i dont know how to solve this problem sorry

Answer 9

That's fine @papadopulosl . All I needed way a background on this so I could do it myself. And thank you @agent0smith for your help :)

Answer 10

Not separated.. they just need the same base

eg x^2, 2x^2, -4x^2 are also similar, base is x^2

eg. x^3y, 5x^3y, -2x^3y are all similar, base is x^3y
