This process is essential in various mathematical operations, including algebra, geometry, and calculus. In this article, we will focus on evaluating the expression 2(6+25)2 \cdot\left(6+2^5\right), which involves a combination of arithmetic operations and exponentiation.

Understanding the Expression

The given expression is 2(6+25)2 \cdot\left(6+2^5\right). To evaluate this expression, we need to follow the order of operations (PEMDAS), which stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.

Breaking Down the Expression

Let's break down the expression into smaller parts:

  • 252^5 represents the exponentiation of 2 to the power of 5.
  • 6+256+2^5 represents the addition of 6 and the result of 252^5.
  • 2(6+25)2 \cdot\left(6+2^5\right) represents the multiplication of 2 by the result of 6+256+2^5.

Evaluating the Exponentiation

The first step in evaluating the expression is to calculate the exponentiation 252^5. This involves raising 2 to the power of 5, which results in:

25=2×2×2×2×2=322^5 = 2 \times 2 \times 2 \times 2 \times 2 = 32

Evaluating the Addition

Next, we need to evaluate the addition 6+256+2^5. Since we have already calculated 252^5 as 32, we can substitute this value into the expression:

6+25=6+32=386+2^5 = 6+32 = 38

Evaluating the Multiplication

Finally, we need to evaluate the multiplication 2(6+25)2 \cdot\left(6+2^5\right). Since we have already calculated 6+256+2^5 as 38, we can substitute this value into the expression:

2(6+25)=238=762 \cdot\left(6+2^5\right) = 2 \cdot 38 = 76

Conclusion

In conclusion, the expression 2(6+25)2 \cdot\left(6+2^5\right) can be evaluated by following the order of operations (PEMDAS). By breaking down the expression into smaller parts, we can calculate the exponentiation, addition, and multiplication to obtain the final result of 76.

Q&A

Q1: What is the order of operations (PEMDAS)?

A1: The order of operations (PEMDAS) is a set of rules that dictates the order in which mathematical operations should be performed. The acronym PEMDAS stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.

Q2: Why is it essential to follow the order of operations?

A2: Following the order of operations is essential to ensure accuracy and avoid errors in mathematical calculations. If the order of operations is not followed, the result of the calculation may be incorrect.

Q3: How do I evaluate an expression with multiple operations?

A3: To evaluate an expression with multiple operations, follow the order of operations (PEMDAS). First, evaluate any expressions inside parentheses, then evaluate any exponents, followed by multiplication and division (from left to right), and finally addition and subtraction (from left to right).

Q4: What is the difference between 252^5 and 525^2?

A4: 252^5 represents the exponentiation of 2 to the power of 5, which equals 32. 525^2 represents the exponentiation of 5 to the power of 2, which equals 25.

Q5: How do I evaluate an expression with a negative exponent?

A5: To evaluate an expression with a negative exponent, rewrite the expression with a positive exponent. For example, 232^{-3} can be rewritten as 123\frac{1}{2^3}, which equals 18\frac{1}{8}.

Q6: What is the final result of the expression 2(6+25)2 \cdot\left(6+2^5\right)?
