Answer:

YOUR ANSWER MATE- 16yx3

Step-by-step explanation:

Explanation:

Explanation:The (r+1)th term Tr+1, in the expansion of (a+b)n is,

Explanation:The (r+1)th term Tr+1, in the expansion of (a+b)n is,Tr+1=nCr⋅an−r⋅br

Explanation:The (r+1)th term Tr+1, in the expansion of (a+b)n is,Tr+1=nCr⋅an−r⋅brSo, in our case, for the read. 4th term, T4 we have,

Explanation:The (r+1)th term Tr+1, in the expansion of (a+b)n is,Tr+1=nCr⋅an−r⋅brSo, in our case, for the read. 4th term, T4 we have,r=3,n=4,a=4y,and,b=x

Explanation:The (r+1)th term Tr+1, in the expansion of (a+b)n is,Tr+1=nCr⋅an−r⋅brSo, in our case, for the read. 4th term, T4 we have,r=3,n=4,a=4y,and,b=x∴T4=4C3⋅(4y)4−3⋅x3

Explanation:The (r+1)th term Tr+1, in the expansion of (a+b)n is,Tr+1=nCr⋅an−r⋅brSo, in our case, for the read. 4th term, T4 we have,r=3,n=4,a=4y,and,b=x∴T4=4C3⋅(4y)4−3⋅x3T4=4⋅4y⋅x3
