make it more clear.

1 answer

To solve the problem using the provided quantities, we'll follow these steps:

  1. Identify the values from the problem:

    • Value 1: \( 0.009430 \)
    • Value 2: \( 43 \)
    • Value 3: \( 10.9 \)
  2. Determine significant digits for each number:

    • \( 0.009430 \): This number has 4 significant digits (the leading zeros are not significant).
    • \( 43 \): This number has 2 significant digits (both digits are significant).
    • \( 10.9 \): This number has 3 significant digits (all digits are significant).
  3. Perform the calculation:

    • We will start by multiplying the three values together: \[ 0.009430 \times 43 \times 10.9 \]
  4. Calculator Work:

    • Start by multiplying \(0.009430 \times 43\): \[ 0.009430 \times 43 = 0.40559 \]

    • Next, multiply the result by \(10.9\): \[ 0.40559 \times 10.9 = 4.409921 \]

  5. Applying Significant Figures: After performing the calculation, we need to round the result \(4.409921\) based on the number with the least significant digits.

    • The number \(0.009430\) has 4 significant figures.
    • The number \(43\) has 2 significant figures.
    • The number \(10.9\) has 3 significant figures.

    The number with the least significant digits is \(43\), which has 2 significant figures.

  6. Rounding the result:

    • The result of \(4.409921\) when rounded to 2 significant figures is \(4.4\).

Final Summary:

  • Calculator Answer: \(4.409921\)
  • Rounded (Significant Figures): \(4.4\)
  • Number of Significant Digits in Final Answer: 2 significant digits.

So, the final answer to the multiplication is 4.4 with 2 significant digits.
