1 answer

To solve the multiplication \( 8.89 \times 1.3886 \times 1.50 \):

  1. Calculate the product using a calculator: \[ 8.89 \times 1.3886 \times 1.50 = 18.511487 \]

  2. Now, determine the correct significant digits:

  • \( 8.89 \) has 3 significant figures.
  • \( 1.3886 \) has 5 significant figures.
  • \( 1.50 \) has 3 significant figures.

The final result must be rounded to the least number of significant figures in the original numbers, which is 3 significant figures (from \( 8.89 \) and \( 1.50 \)).

The value \( 18.511487 \) rounded to 3 significant figures is 18.5.

Thus, the answers are:

  • A. \( 18.511487 \) (calculator answer)
  • B. \( 18.5 \) (correct significant digit answer)
