If x = 2, y = - 1, the value of this monomial is 32, find this monomial
∵ this quintic monomial with the letters X and y, the exponent of X is 3, the exponent of Y is 2, let this monomial be ax3y2, ∵ when x = 2, y = - 1, the value of this monomial is 32, ∵ 8A = 32, the solution is a = 4, so this monomial is 4x3y2
Write all the monomials with the letters A and B, the coefficient is - 2 and the degree is 3
-2a²b,-2ab²
Write all the monomials with the letters A and B, the coefficient of - 2 and the degree of 3
-2A ^ 2B or - 2Ab ^ 2
