The first problem of monomial elementary school The following statement is correct: A. (a + 2) / 3 is a monomial, b.b/a is a monomial, C. (M + 2) a is a monomial, D. - 3x ˇ 2Y / π is a monomial, note that D. is a negative number

Junior high school mathematics mainly studies integral, fraction and quadratic radical. Among them, integral is divided into monomial and polynomial. Therefore, we must judge whether it is integral before judging monomial
A is binomial, B is fractional, C is binomial, D is monomial
A monomial is not only an unknown number, such as XYZ. The basis of judgment is that there is no + - Method in the formula, and such a formula is a monomial
