In elementary algebra, the binomial theorem describes the algebraic expansion of powers of a binomial According to the theorem, it is possible to expand the polynomial n into a sum involving terms of the form axbyc, where the exponents b and c are nonnegative integers with b c = n, and the coefficient a of each term is a specific positive integer depending on n and b For example, 4 = x 4 4 x 3 y 6 x 2 y 2 4 x y 3 y 4 {\displaystyle ^{4}=x^{4}4x^{3}y6x^{2}y^{2}4xy^{3}yV(x, y = 0) = 0 (grounded bottom plate) 2 V(x, y = π) = 0 (grounded top plate) 3 V(x = 0, y) = V 0 (y) (plate at x = 0) 4 V → 0 when x → ∞ These four boundary conditions specify the value of the potential on all boundaries surrounding the slot and are therefore sufficient to uniquely determine the solution of Laplace's equationWhat is the coefficient of x 2 y 2 z 3 in the expansion of (x y z) 7?
