Which term in the expansion of (2-3x)^(19) has algebrically the last coefficients ? |
|
Answer» `10^(th)` Using `r le (n+1)/(1+|(a)/(bx)|)`, we get `RLE(19+1)/(1+|2/3|)rArr r le 12` Therefore, `T_(13)` and `T_(12)` have numerically the greatest conefficient. `T_(12)` is ALGEBRICALLY the least as it is followedby negative sign. |
