A) The terms \[4{{x}^{2}}y\] and \[3x{{y}^{2}}\] are like terms.
B) The coefficient of \[{{y}^{2}}\] in the expression \[-2{{x}^{2}}y+8x{{y}^{2}}+39\] is\[8x\].
C) \[3,\,\,x,\,\,{{x}^{2}}\]and y are factors of\[3{{x}^{2}}y\].
D) The expression \[15{{p}^{2}}q+8p{{q}^{2}}+42pq+99\]contains 4 terms.
Correct Answer: A
Solution :
Two terms are called like terms only when their variable part is the same. In \[4{{x}^{2}}y,\]variable is \[{{x}^{2}}y\] whereas in \[3x{{y}^{2}},\] variable is\[x{{y}^{2}}\].
