Certainly! Here's a clear, step-by-step solution based on what I can see in the image: --- ### **Step 1: Understanding the Required Information** - The question asks how many significant digits are in the value .00630. - **Significant digits** are all non-zero digits, any zeros between non-zero digits, and any trailing zeros in the decimal portion. **Explanation:** In .00630: - Leading zeros (the zeros before the 6) are **not** significant. - The digits "6", "3", and the trailing "" (to the right of the decimal and after a non-zero digit) **are significant**. --- ### **Step 2: Counting the Significant Digits** - "6" is significant. - "3" is significant. - The trailing "" is significant because it comes after a decimal and after a non-zero digit. **Explanation:** This means there are **3 significant digits** in the value .00630. --- ## **Final Answer** There are **3 significant digits** in .00630.

Sure! Let's solve the problem step-by-step. --- ### **Step 1: Identify the Components of the Expression** - The expression given is \( \frac{4}{2} + 3 \times 2 \). - We need to follow the order of operations (PEMDAS/BODMAS). **Explanation:** First, we should handle the division and multiplication before performing addition: 1. **Division:** \( \frac{4}{2} = 2 \) 2. **Multiplication:** \( 3 \times 2 = 6 \) Now, we can rewrite the expression with these results. --- ### **Step 2: Perform the Addition** - The expression now is \( 2 + 6 \). **Explanation:** Now, we can simply add the two results: \[ 2 + 6 = 8 \] --- ## **Final Answer** The final result of the expression \( \frac{4}{2} + 3 \times 2 \) is **8**.
