Introduction

In mathematics, expressions are used to represent a value or a relationship between values. Evaluating an expression involves simplifying it to a single value. In this article, we will focus on evaluating the expression 42βˆ’6(7βˆ’10)4^2 - 6(7 - 10) and determining its equivalent value.

Understanding the Expression

The given expression is 42βˆ’6(7βˆ’10)4^2 - 6(7 - 10). To evaluate this expression, we need to follow the order of operations (PEMDAS):

  1. Parentheses: Evaluate the expressions inside the parentheses.
  2. Exponents: Evaluate any exponential expressions.
  3. Multiplication and Division: Evaluate any multiplication and division operations from left to right.
  4. Addition and Subtraction: Evaluate any addition and subtraction operations from left to right.

Evaluating the Expression

Let's start by evaluating the expression inside the parentheses: 7βˆ’107 - 10. This expression is equal to βˆ’3-3.

Now, we can rewrite the original expression as 42βˆ’6(βˆ’3)4^2 - 6(-3).

Evaluating Exponents

Next, we need to evaluate the exponential expression 424^2. This expression is equal to 1616.

Evaluating Multiplication and Division

Now, we can rewrite the expression as 16βˆ’6(βˆ’3)16 - 6(-3).

Evaluating Multiplication

To evaluate the multiplication operation, we need to multiply 66 by βˆ’3-3. This operation is equal to βˆ’18-18.

Evaluating Addition and Subtraction

Finally, we can evaluate the addition and subtraction operations. We have 16βˆ’(βˆ’18)16 - (-18). To subtract a negative number, we can add its positive counterpart. Therefore, this expression is equal to 16+1816 + 18.

Final Evaluation

The final evaluation of the expression 42βˆ’6(7βˆ’10)4^2 - 6(7 - 10) is 16+1816 + 18, which is equal to 3434.

Conclusion

In this article, we evaluated the expression 42βˆ’6(7βˆ’10)4^2 - 6(7 - 10) and determined its equivalent value. By following the order of operations and simplifying the expression, we found that the equivalent value is 3434.

Frequently Asked Questions

  • What is the order of operations? The order of operations is a set of rules that tells us which operations to perform first when evaluating an expression. The order of operations is:
    1. Parentheses
    2. Exponents
    3. Multiplication and Division
    4. Addition and Subtraction
  • How do I evaluate an expression with parentheses? To evaluate an expression with parentheses, we need to evaluate the expressions inside the parentheses first. Then, we can evaluate the rest of the expression.
  • What is the difference between βˆ’3-3 and βˆ’(βˆ’3)-(-3)? The expression βˆ’(βˆ’3)-(-3) is equal to 33, not βˆ’3-3. This is because subtracting a negative number is the same as adding its positive counterpart.

Final Answer

The final answer is 34\boxed{34}.

Introduction

Q&A

Q: What is the order of operations?

A: The order of operations is a set of rules that tells us which operations to perform first when evaluating an expression. The order of operations is: 1. Parentheses 2. Exponents 3. Multiplication and Division 4. Addition and Subtraction

Q: How do I evaluate an expression with parentheses?

A: To evaluate an expression with parentheses, we need to evaluate the expressions inside the parentheses first. Then, we can evaluate the rest of the expression.

Q: What is the difference between βˆ’3-3 and βˆ’(βˆ’3)-(-3)?

A: The expression βˆ’(βˆ’3)-(-3) is equal to 33, not βˆ’3-3. This is because subtracting a negative number is the same as adding its positive counterpart.

Q: How do I evaluate an expression with multiple operations?

A: To evaluate an expression with multiple operations, we need to follow the order of operations. We start by evaluating the expressions inside the parentheses, then we evaluate any exponential expressions, followed by any multiplication and division operations, and finally any addition and subtraction operations.

Q: What is the difference between 232^3 and 2Γ—2Γ—22 \times 2 \times 2?

A: The expressions 232^3 and 2Γ—2Γ—22 \times 2 \times 2 are equal. The exponentiation operation 232^3 is equivalent to multiplying 22 by itself three times.

Q: How do I evaluate an expression with variables?

A: To evaluate an expression with variables, we need to substitute the values of the variables into the expression. For example, if we have the expression x+2x + 2, and we know that x=3x = 3, we can substitute xx with 33 to get 3+23 + 2.

Q: What is the difference between βˆ’5+3-5 + 3 and βˆ’5βˆ’3-5 - 3?

A: The expressions βˆ’5+3-5 + 3 and βˆ’5βˆ’3-5 - 3 are not equal. The expression βˆ’5+3-5 + 3 is equal to βˆ’2-2, while the expression βˆ’5βˆ’3-5 - 3 is equal to βˆ’8-8.

Q: How do I evaluate an expression with fractions?

A: To evaluate an expression with fractions, we need to follow the order of operations. We start by evaluating any exponential expressions, followed by any multiplication and division operations, and finally any addition and subtraction operations.

Q: What is the difference between 12+14\frac{1}{2} + \frac{1}{4} and 12βˆ’14\frac{1}{2} - \frac{1}{4}?

A: The expressions 12+14\frac{1}{2} + \frac{1}{4} and 12βˆ’14\frac{1}{2} - \frac{1}{4} are not equal. The expression 12+14\frac{1}{2} + \frac{1}{4} is equal to 34\frac{3}{4}, while the expression 12βˆ’14\frac{1}{2} - \frac{1}{4} is equal to 14\frac{1}{4}.
