Which of the following are similar terms?
A.3xy, 3x^2y^3
B.-4a, -6b
C.15a^2b^2 , -15a^2b^2
D.9x^2y, 8xy^2​

Sagot :

C. 15a²b², -15a²b²

Why?

 - Well, similar terms looks for the identical variables and it does not include the coefficients. Letter C is the only one with the exact unknown factors.

  • A does have the same variable but the second term has exponents and it changes the whole thing, they are no longer the same.
  • B has the same coefficients but as explained, variables is what's needed to be identical.
  • D is almost like A, if you change the position of the exponent it can create a huge difference.
