Introduction

In algebra, monomies are a fundamental concept that plays a crucial role in understanding and solving mathematical equations. A monomie is a single term that consists of a coefficient, a variable, and an exponent. When we multiply monomies, we need to follow specific rules to simplify the expression and obtain the final result. In this article, we will delve into the world of monomies and explore the multiplication result of monomies, specifically the expression 5AB*(-3A).

Understanding Monomies

A monomie is a single term that consists of three components:

Coefficient: A numerical value that multiplies the variable.
Variable: A letter or symbol that represents a quantity.
Exponent: A power or index that indicates the number of times the variable is multiplied by itself.

For example, the monomie 3x^2 has a coefficient of 3, a variable of x, and an exponent of 2.

Multiplication of Monomies

When we multiply monomies, we need to follow the distributive property, which states that:

a(b + c) = ab + ac

In the context of monomies, this means that we can multiply each term in the expression by the other term.

Multiplication of 5AB and -3A

Now, let's apply the distributive property to the expression 5AB*(-3A).

5AB*(-3A) = 5AB * (-3A)

Using the distributive property, we can rewrite the expression as:

5AB * (-3A) = (5A)(B)(-3A)

Now, we can simplify the expression by multiplying the coefficients and variables:

(5A)(B)(-3A) = -15AB^2A

Simplifying the Expression

When we multiply monomies, we need to simplify the expression by combining like terms. In this case, we have two variables, A and B, and two exponents, 1 and 2.

-15AB^2A = -15A^2B2

Conclusion

In conclusion, the multiplication result of monomies is a fundamental concept in algebra that requires a deep understanding of the distributive property and the rules of exponentiation. By following the steps outlined in this article, we can simplify complex expressions and obtain the final result.
