Question

the middle term of the expansion
$(ax + ay)^{n}$
is
$14580x ^{3} y^{3}$
find the value of a and the value of n, where a, n are elements of N.​

Answer 1

Answer:

Hello,

a=3

Step-by-step explanation:

Since the middle term is x^3y^3 ==> n=6

Coefficient of  x^3y^3 is 20 (triangle de Pascal)

So a^6= 14580/20=729 ==> a=3
