Question

May anyone please help me with my math , Thank you very much. the choices are just S or N :)​

Answer 1

1. N, 2. S, 3. S, 4. S, 5. N*

Explanation:

By "similar," I'm assuming you mean the same thing as "like" terms. Those are exactly the same (same variables and same exponents) but could have different coefficients (the number in front).

1. N variables are not the same

2. S variables are the same, exponents are the same

3. S same variables; same exponents (x^3 y^2 is the same as y^2 x^3)

4. S

5. N first term has z^2 in it; the second does not

*P.S. I'm having some trouble distinguishing your "two" from "zee."

If the 2nd expression is

`(1z zyx)/(2)` then the terms are similar.
