Answer:
240
Step-by-step explanation:
The x^k term will be ...
(6Ck)(x^k)(4^(6-k))
For k=4, this is ...
(6C4)(x^4)(4^2) = 15·16·x^4 = 240x^4
The coefficient of x^4 is 240.
_____
nCk = n!/(k!(n-k)!)
Answer:
0,11
Step-by-step explanation:
y^2-11y=0
y(y-11)=0 we have transformed the equation into a product
a product can be zero only if one of the factors is 0
so the two solutions are
y=0
and y-11=0 y=11
