Answer:
The correct option is;
False
Step-by-step explanation:
The coefficient of x^k·y^(n-k) is nk, False
The kth coefficient of the binomial expansion, (x + y)ⁿ is
Where;
k = r - 1
r = The term in the series
For an example the expansion of (x + y)⁵, we have;
(x + y)⁵ = x⁵ + 5·x⁴·y + 10·x³·y² + 10·x²·y³ + 5·x·y⁴ + y⁵
The third term, (k = 3) coefficient is 10 while n×k = 3×5 = 15
Therefore, the coefficient of x^k·y^(n-k) for the expansion (x + y)ⁿ = not nk
Answer:
what's your question I can't understand
Answer:
last one
Step-by-step explanation:
Answer:
n x n x 6 and n x 6 x n
Step-by-step explanation:
Volume is a way of saying a 3 dimensional cubes mass. So it's extra dimension would be height which is 6 and the length and width is n so you would multiply them like this l x w x h.
