Question

Which of the following pairs of terms is a pair of like terms
(a)7xy, 14yx (b)m?p, mp² (c)6xz,12×x²z²
(d)-13x, -13y​

Answer 1

Answer:

(a)

Step-by-step explanation:

For (a),

we have the term "xy" in both "7xy" and "14yx" (xy = yx, just like 2x3 = 3x2)

So this is correct.

For (b),(c) and (d),

we don't have two same terms  

(b): Take "mp²" as an example, we have "mp²" but the other one doesn't have a "p²" --> wrong

(c): ''xz" ≠ "x²z²" --> wrong

(d) x ≠ y --> wrong
