The correct Answer is:
To evaluate \((-5)^3\), we will follow these steps: ### Step-by-Step Solution: 1. **Identify the expression**: We start with the expression \((-5)^3\). **Hint**: Remember that the exponent indicates how many times the base (in this case, \(-5\)) is multiplied by itself. 2. **Rewrite the expression**: We can express \((-5)^3\) as \((-1) \times (5)^3\). This helps us separate the negative sign from the base. **Hint**: Breaking down the expression can make it easier to manage the negative sign and the positive base. 3. **Apply the exponent**: Now we can distribute the exponent to both parts: \[ (-1)^3 \times (5)^3 \] **Hint**: When you have a product, you can apply the exponent to each factor separately. 4. **Calculate \((-1)^3\)**: Since \(-1\) raised to an odd power remains \(-1\): \[ (-1)^3 = -1 \] **Hint**: Remember that \(-1\) raised to an odd exponent results in \(-1\). 5. **Calculate \(5^3\)**: Now calculate \(5^3\): \[ 5^3 = 5 \times 5 \times 5 \] First, calculate \(5 \times 5 = 25\), and then multiply \(25 \times 5 = 125\). **Hint**: You can break down the multiplication into smaller steps for easier calculations. 6. **Combine the results**: Now, combine the results: \[ (-1) \times (125) = -125 \] **Hint**: Remember that multiplying a negative number by a positive number results in a negative number. ### Final Answer: Thus, the value of \((-5)^3\) is \(-125\).
