Simplify The Expression: 9 + 8 ( N + 1 9 + 8(n + 1 9 + 8 ( N + 1 ]

$$

Introduction

In mathematics, simplifying expressions is a crucial skill that helps us solve problems more efficiently. It involves rewriting an expression in a simpler form, often by combining like terms or removing unnecessary components. In this article, we will simplify the expression $9 + 8(n + 1)$ using various mathematical techniques.

Understanding the Expression

The given expression is $9 + 8(n + 1)$. To simplify this expression, we need to understand its components. The expression consists of two terms: a constant term $9$ and a variable term $8(n + 1)$. The variable term is a product of two numbers: $8$ and $(n + 1)$.

Distributive Property

To simplify the expression, we can use the distributive property, which states that for any real numbers $a$, $b$, and $c$, $a(b + c) = ab + ac$. We can apply this property to the variable term $8(n + 1)$.

8(n + 1) = 8n + 8

Now, we can rewrite the original expression as:

$$9 + 8(n + 1) = 9 + 8n + 8$$

Combining Like Terms

The expression $9 + 8n + 8$ consists of three terms: $9$, $8n$, and $8$. We can combine the constant terms $9$ and $8$ to get a single constant term.

9 + 8 = 17

So, the expression becomes:

$$9 + 8n + 8 = 17 + 8n$$

Final Simplified Expression

The final simplified expression is $17 + 8n$. This expression is simpler than the original expression $9 + 8(n + 1)$, as it has fewer terms and is easier to work with.

Conclusion

Simplifying expressions is an essential skill in mathematics that helps us solve problems more efficiently. By applying the distributive property and combining like terms, we can simplify the expression $9 + 8(n + 1)$ to get the final simplified expression $17 + 8n$. This technique can be applied to various mathematical expressions, making it an essential tool for problem-solving.

Introduction

In our previous article, we simplified the expression $9 + 8(n + 1)$ using various mathematical techniques. In this article, we will answer some frequently asked questions (FAQs) related to simplifying expressions.

Q&A

Q: What is the distributive property?

A: The distributive property is a mathematical concept that allows us to multiply a single term by multiple terms. It states that for any real numbers $a$, $b$, and $c$, $a(b + c) = ab + ac$.

Q: How do I apply the distributive property to simplify an expression?

A: To apply the distributive property, you need to multiply the single term by each of the multiple terms. For example, if you have the expression $8(n + 1)$, you can apply the distributive property by multiplying $8$ by each of the terms inside the parentheses: $8n$ and $1$.

Q: What is the difference between combining like terms and simplifying an expression?

A: Combining like terms involves adding or subtracting terms that have the same variable and coefficient. Simplifying an expression involves rewriting it in a simpler form, often by combining like terms or removing unnecessary components.

Q: How do I know if I can combine like terms?

A: You can combine like terms if the terms have the same variable and coefficient. For example, you can combine the terms $3x$ and $2x$ because they have the same variable ($x$) and coefficient ($3$ and $2$).

Q: What are some common mistakes to avoid when simplifying expressions?

A: Some common mistakes to avoid when simplifying expressions include:

• Forgetting to distribute a term to multiple terms
• Not combining like terms
• Making algebraic errors, such as factoring or expanding incorrectly

Q: How do I check my work when simplifying an expression?

A: To check your work, you can plug the simplified expression back into the original equation and see if it is true. You can also use algebraic manipulations, such as factoring and expanding, to verify the simplified expression.

Q: Can I simplify expressions with variables that have exponents?
