It isnC0*A^n*b^0 + nC1*A^(n-1)*b^1 + ... + nCr*A^(n-r)*b^r + ... + nCn*A^0*b^n where nCr = n!/[r!*(n-r)!]
The coefficient of x^r in the binomial expansion of (ax + b)^n isnCr * a^r * b^(n-r)where nCr = n!/[r!*(n-r)!]
Yup, its official, usher is the king of r n b.
POP, R n B

The answer to "N in the middle of i A R B" in the rebus puzzle is "IN." It indicates that the letter "N" is positioned in the center of the letters "i," "A," "R," and "B." Therefore, the solution highlights the placement of "N" within the context.
T r+1 = (n / r) (a ^n-r) x (b)^r
