Problem 15
Question
In \(11-22,\) find the value of each expression when \(x \neq 0\) $$ (4 x)^{0} $$
Step-by-Step Solution
Verified Answer
The value is 1.
1Step 1: Identify the Expression
The expression we need to evaluate is \((4x)^0\).
2Step 2: Apply the Zero Exponent Rule
According to the Zero Exponent Rule, any non-zero base raised to the power of zero is 1. This means \((4x)^0 = 1\) as long as \(x eq 0\).
3Step 3: Confirm Conditions
The problem specifies \(x eq 0\) which satisfies the condition required for the Zero Exponent Rule to hold true. Thus, the expression evaluates correctly.

Exponents
Understanding exponents is crucial in mathematics as they simplify complex multiplication. An exponent indicates how many times a number, called the base, is multiplied by itself. For example, in the expression \(3^4\), 3 is the base and 4 is the exponent, meaning \(3 \times 3 \times 3 \times 3 = 81\).
In the example from the exercise, the expression is \((4x)^0\). The 0 is the exponent. Here, the base is \(4x\), which normally would involve multiplying 4 and x together a specified number of times. However, exponents can also be zero, leading us to a special rule, called the Zero Exponent Rule.

- Exponents indicate repeated multiplication.
- They consist of a base and an exponent.
Evaluate Expressions
Evaluating expressions means finding their value by substituting variables and using mathematical rules appropriately. In algebra, this requires understanding how to work with variables and different operations such as addition, subtraction, multiplication, and exponents.
When evaluating the expression \((4x)^0\), understanding that \(x eq 0\) is key. This means any value except zero can be substituted for \(x\), and the expression will still comply with the rules of exponents. By applying known mathematical rules, like the Zero Exponent Rule, we can simplify and find the value of an algebraic expression more easily.

- Substitute given values for variables carefully.
- Apply known mathematical rules systematically.
Algebraic Rules
Algebraic rules like the Zero Exponent Rule are foundational for working with expressions. The Zero Exponent Rule states that any non-zero base raised to the zero power equals 1.
In the provided problem, the rule is applied to the expression \((4x)^0\). Here, since \(4x\) is a non-zero entity as long as \(x eq 0\), the rule dictates that the entire expression equals 1. This holds true regardless of the complexity of the base, as the rule focuses solely on the exponent.

- Rules help simplify expressions.
