Answer:
Convergent; 81
Step-by-step explanation:
r = term2/term1 = 8/9
8/9 < 1 so convergent
Sum = 9/(1 - 8/9)
= 9/(1/9) = 81
93

The coefficients are 8 , 12, 6, 1
The coefficients are 16, 96, 216, 216, 81
The coefficients are 27, 54,36 , 8
= x^4+4x^3y+6x^2y^2+4xy^3+y^4
The coefficients are 1, 4, 6, 4, 1
