Question

Evaluate. $$\left(2 x^{2}-8 x+32\right)^{0}$$

Short answer

\((2x^2 - 8x + 32)^0 = 1\) for all values of \(x\).

Step-by-step solution

Understand the Zero Exponent Rule

Recall the rule that any nonzero expression raised to the power of zero is equal to one. This is written as for any nonzero number 'a', it's true that \(a^{0} = 1\).

Apply the Zero Exponent Rule

The expression \(2x^2 - 8x + 32\) is raised to the power of zero. According to the zero exponent rule, regardless of what the base (\(2x^2 - 8x + 32\)) is, as long as it's not zero, its value raised to the zero power will be 1.

Provide the Final Answer

Since the base here \(2x^2 - 8x + 32\) is not zero for all values of \(x\), we can conclude that \((2x^2 - 8x + 32)^0 = 1\).

Key concepts

Exponents in Mathematics

Exponents, also known as powers, are a fundamental concept in mathematics, often introduced in algebra. They provide a shorthand way to express repeated multiplication of the same number. For instance, when we write \(5^3\), it means \(5 \times 5 \times 5\), the number 5 multiplied by itself three times.

Understanding the law of exponents is essential for simplifying algebraic expressions and solving a wide range of mathematical problems. One of the key exponent rules is the Zero Exponent Rule, which states that any non-zero base raised to the power of zero equals one, mathematically represented as \(a^0 = 1\), where 'a' is a nonzero number. This rule is exceptionally useful in simplifying expressions and is a fundamental property that students must grasp to become proficient in mathematics.

Algebraic Expressions

Algebraic expressions are combinations of variables, numbers, and arithmetic operations like addition, subtraction, multiplication, and division. In an expression like \(2x^2 - 8x + 32\), 'x' is a variable which can represent different numbers.

Handling algebraic expressions proficiently requires recognizing patterns and applying the correct rules. For example, the distributive property or combining like terms are tools frequently used. When exponents are involved, understanding the specific rules governing them, like the Zero Exponent Rule, allows for elegant simplification and facilitates the overall process of mathematical problem solving.

Mathematical Problem Solving

Problem solving is at the core of mathematics. It involves understanding the problem, planning a route to the solution, executing the plan, and then looking back to check the results. If an algebraic expression with an exponent is part of the problem, like \((2x^2 - 8x + 32)^0\), we must apply the correct rules.

To efficiently solve problems with such expressions, students should:

• Identify the structure of the problem (in this case, an exponent rule needs to be applied).
• Recall the relevant mathematical rules (like the Zero Exponent Rule).
• Apply the rule correctly to simplify the expression (resulting in the answer 1, due to the exponent being zero).
• Verify the solution in the context of the problem to ensure it makes sense.

Instilling the principles of problem solving, especially when dealing with exponents and algebraic expressions, not only helps in achieving correct answers but also builds a strong foundation for more complex mathematics.
