Read Solution (Total 3)
-
- out of given options
x^2 has the greatest coefficient in the expansion of (1+x/2)^10. - 12 years agoHelpfull: Yes(1) No(0)
- COEFFICIENT OF X^3=10C7(X/2)^3=15X^3
IT IS THE GREATER - 12 years agoHelpfull: Yes(1) No(1)
- the coefficients are
1, 5, 11.25, 15, 13.125, 7.875, and so on. it decreases as we move
so, the answer is 15 and hence, x^3 - 12 years agoHelpfull: Yes(0) No(0)
