Which of the following terms appear in the expansion of (x + y)10? The letter a in each term represents a real constant. A. ax3y7 B. ay5 C. ax5 D. ax5y
Answer:
The correct option is:
A. \(ax^3y^7\)
Step-by-step explanation:
We are asked which term would appear in the expansion of:
\((x+y)^{10}\)
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. \(ax^3y^7\) sum of powers=3+7=10
B. \(ay^5\) sum of powers=5
C. \(ax^5\) sum of powers=5
D. \(ax^5y\) sum of powers=5+1=6
Hence, the correct option is:
A. \(ax^3y^7\)
