What is the degree of the third power of π x? What is the coefficient?


The degree of the third power of π 3 is 3, and the coefficient is π 3



In the expansion of binomial (x + y) to the power of N, the coefficient of the power of n-2 of X is 44 larger than that of the power of N-1 of X, then n=


The coefficient of n-2 power of X and 2 power of Y is
C(n,2)
The N-1 power of X and the coefficient of Y are
C(n,1)
C(n,2)-C(n,1)=44
n(n-1)/2-n=44
Solve the equation: n = 11, or n = - 8 (rounding off)



-[(2a-b) 4] square


-[(2a-b) 4] square
=-(2a-b)^8
