Evaluate The Expression With A Negative Base.$\[ (-4)^0 = \square \\]
=====================================================
Introduction
In mathematics, the concept of exponents is crucial for solving various types of problems. Exponents are used to represent repeated multiplication of a number. However, when it comes to negative bases, the rules of exponents can become a bit more complex. In this article, we will evaluate the expression with a negative base and explore the properties of exponents.
Understanding Exponents
Exponents are a shorthand way of representing repeated multiplication of a number. For example, the expression 2^3 can be read as "2 to the power of 3" or "2 multiplied by itself 3 times." The result of this expression is 222 = 8.
Negative Bases
When it comes to negative bases, the rules of exponents can become a bit more complex. A negative base is a number that is less than zero. For example, -4 is a negative base. When we raise a negative base to a power, we need to consider the properties of exponents.
Evaluating the Expression
The expression we need to evaluate is (-4)^0. To evaluate this expression, we need to understand the properties of exponents. When a number is raised to the power of 0, the result is always 1. This is a fundamental property of exponents.
The Zero Exponent Rule
The zero exponent rule states that any number raised to the power of 0 is equal to 1. This rule applies to both positive and negative numbers. For example, 2^0 = 1 and (-2)^0 = 1.
Applying the Zero Exponent Rule
Now that we understand the zero exponent rule, we can apply it to the expression (-4)^0. According to the rule, any number raised to the power of 0 is equal to 1. Therefore, (-4)^0 = 1.
Conclusion
In conclusion, evaluating the expression with a negative base requires an understanding of the properties of exponents. The zero exponent rule states that any number raised to the power of 0 is equal to 1. By applying this rule, we can evaluate the expression (-4)^0 and determine that the result is 1.

Introduction
In our previous article, we discussed evaluating expressions with negative bases. We explored the properties of exponents and the zero exponent rule, which states that any number raised to the power of 0 is equal to 1. In this article, we will answer some frequently asked questions about evaluating expressions with negative bases.
Q&A
Q: What is the value of (-4)^3?
A: To evaluate this expression, we need to apply the exponent rule for negative bases. The rule states that (-a)^n = -a^n if n is odd and (-a)^n = a^n if n is even. Since 3 is an odd number, we can apply the rule to get (-4)^3 = -4^3 = -64.
Q: What is the value of (-2)^0?
A: According to the zero exponent rule, any number raised to the power of 0 is equal to 1. Therefore, (-2)^0 = 1.
Q: Can the exponent rule for negative bases be applied to fractions?
A: Yes, the exponent rule for negative bases can be applied to fractions. For example, (-1/2)^3 = -1/8.
Q: What is the value of (-3)^4?
A: To evaluate this expression, we need to apply the exponent rule for negative bases. Since 4 is an even number, we can apply the rule to get (-3)^4 = 3^4 = 81.
Q: What is the value of (-5)^0?
A: According to the zero exponent rule, any number raised to the power of 0 is equal to 1. Therefore, (-5)^0 = 1.
Q: Can the exponent rule for negative bases be applied to decimals?
A: Yes, the exponent rule for negative bases can be applied to decimals. For example, (-0.5)^3 = -0.125.
Q: What is the value of (-2)^5?
A: To evaluate this expression, we need to apply the exponent rule for negative bases. Since 5 is an odd number, we can apply the rule to get (-2)^5 = -2^5 = -32.
