Which expression represents the sixth term in the binomial expansion of (5y + 3)10? a. 10c5(5y)5(3)5 b. 10c6(5y)4(3)6 c. 510c5(y)5(3)5 d. 510c6(y)4(3)6

we are given binomial expression as

now, we can use formula

rth term binomial expansion formula of (a+b)^n

now, we can compare and find a , b , n and r

we get

a=5y

b=3

n=10

r=6

so, we can plug it in formula

and we get

we can simplify it

so, option-B..........Answer

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
