Answer:

C) 210

Step-by-step explanation:

Using binomial expansion for

[tex](x+y)^10[/tex]

we have general term

[tex]T_{r+1} =10Cr x^{10-r} y^r,r=0,1,2,3....10[/tex]

Now we want the term which has 10-r =6 or r =4

Hence coefficient would be

10C4

= [tex]\frac{10(9)(8)(7)}{1(2)(3)(4)} \\=210[/tex]

Hence answer is option C

210
