Understanding Monomials and Their Products

In mathematics, a monomial is an algebraic expression consisting of a single term, which can be a number, a variable, or a product of numbers and variables. When we multiply monomials, we need to apply the rules of exponents and variables to simplify the resulting expression. In this article, we will explore the product of the monomials given in the following expressions:

${-18(a b)^{13}}$
${-18 a^7 b^6}$
${-18 a^{10} b^6}$
${-18 a^7 b^9}$

The Product of Monomials: A Step-by-Step Guide

To find the product of the monomials, we need to follow the rules of exponents and variables. Here are the steps to simplify each expression:

Expression 1: ${-18(a b)^{13}}$

To simplify this expression, we need to apply the power rule of exponents, which states that ${(ab)^n = a^nb^n}$ . Therefore, we can rewrite the expression as:

${-18(a^{13} b^{13})}$

Now, we can multiply the coefficients and variables separately:

${-18 \cdot a^{13} \cdot b^{13}}$

The final answer is ${-18a^{13}b^{13}}$ .

Expression 2: ${-18 a^7 b^6}$

This expression is already simplified, so we can move on to the next one.

Expression 3: ${-18 a^{10} b^6}$

To simplify this expression, we need to multiply the coefficients and variables separately:

${-18 \cdot a^{10} \cdot b^6}$

The final answer is ${-18a^{10}b^6}$ .

Expression 4: ${-18 a^7 b^9}$

To simplify this expression, we need to multiply the coefficients and variables separately:

${-18 \cdot a^7 \cdot b^9}$

The final answer is ${-18a^7b^9}$ .

Conclusion

In conclusion, the product of the monomials given in the expressions is:

${-18a^{13}b^{13}}$
${-18 a^7 b^6}$
${-18a^{10}b^6}$
${-18a^7b^9}$

By following the rules of exponents and variables, we can simplify each expression and find the product of the monomials.

Frequently Asked Questions

Q: What is a monomial?

A: A monomial is an algebraic expression consisting of a single term, which can be a number, a variable, or a product of numbers and variables.

Q: How do I multiply monomials?

A: To multiply monomials, you need to apply the rules of exponents and variables. You can multiply the coefficients and variables separately, and then simplify the resulting expression.

Q: What is the power rule of exponents?

A: The power rule of exponents states that ${(ab)^n = a^nb^n}$ . This means that when you raise a product of two variables to a power, you can raise each variable to that power separately.

Q: How do I simplify an expression with multiple variables?

A: To simplify an expression with multiple variables, you need to apply the rules of exponents and variables. You can multiply the coefficients and variables separately, and then simplify the resulting expression.

Q: What is the difference between a monomial and a polynomial?

A: A monomial is an algebraic expression consisting of a single term, while a polynomial is an algebraic expression consisting of multiple terms.

Q: How do I add and subtract monomials?

A: To add and subtract monomials, you need to combine like terms. Like terms are terms that have the same variable and exponent.

Q: What is the distributive property of multiplication over addition?

A: The distributive property of multiplication over addition states that a(b + c) = ab + ac. This means that you can multiply a single term by the sum of two or more terms.

Q: How do I apply the distributive property to monomials?

A: To apply the distributive property to monomials, you need to multiply each term in the expression by the single term.

Q: What is the associative property of multiplication?

A: The associative property of multiplication states that (ab)c = a(bc). This means that you can change the order of the terms in a multiplication expression without changing the result.

Q: How do I apply the associative property to monomials?

A: To apply the associative property to monomials, you need to change the order of the terms in the expression without changing the result.

Q: What is the commutative property of multiplication?

A: The commutative property of multiplication states that ab = ba. This means that you can change the order of the terms in a multiplication expression without changing the result.

Q: How do I apply the commutative property to monomials?

A: To apply the commutative property to monomials, you need to change the order of the terms in the expression without changing the result.

Q: What is the order of operations?

A: The order of operations is a set of rules that tells you which operations to perform first when you have multiple operations in an expression. The order of operations is:

Parentheses
Exponents
Multiplication and Division
Addition and Subtraction

Q: How do I apply the order of operations to monomials?

A: To apply the order of operations to monomials, you need to perform the operations in the correct order.

Conclusion

In conclusion, monomials and their products are an important part of algebra. By understanding the rules of exponents and variables, you can simplify expressions and solve problems. Remember to apply the distributive property, associative property, commutative property, and order of operations to monomials to get the correct result.
