What is the coefficient of the x9y-term in the binomial expansion of (2y 4x3)4?

Sonbull [250]

The binomial expansion: $T_{k+1}= \frac{n!}{(n-k+1 )!}a^{n-k} b^{k}$
a = 2y, b = 4 x^3, n = 4
( x )^3k = x^ 9
k = 3
$T_{4}= \frac{24}{6}(2y) ^{3-1} (4x^{3} )^{3}$
$T4=512 x^{9} y$
Answer: the coefficient is 512.

1. f(x) = 2x + 6 Evaluate f(2)

fredd [130]

1) f(x)=2x+6
f(2)=2(2)+6
=4+6
=10

2)f(x)=3x
f(a+1)=3(a+1)
=3a+3
3)f(x)=3x-1 and g(x)=5x+3

f(2)=3(2)-1
f(2)=6-1
=5
g(3)=5x+3
=5(3)+32
=15+3
=18

f(2)+f(3)=5+18
=23.
