Answer:
The correct option is:
A. [tex]ax^3y^7[/tex]
Step-by-step explanation:
We are asked which term would appear in the expansion of:
[tex](x+y)^{10}[/tex]
Clearly all the terms of this expansion will have the sum of powers of x and y =10
In our given options the sum of powers of x and y are:
A. [tex]ax^3y^7[/tex] sum of powers=3+7=10
B. [tex]ay^5[/tex] sum of powers=5
C. [tex]ax^5[/tex] sum of powers=5
D. [tex]ax^5y[/tex] sum of powers=5+1=6
Hence, the correct option is:
A. [tex]ax^3y^7[/tex]
