Question

Select the expression that makes the equation true.
(9. 109) · (–2 . 10⁻³) =

Answer 1

The expression that makes the equation true is (9.109) · (–2.10⁻³) = 5.0 × 10⁻⁹. To solve this, multiply the two numbers together, add the exponents of 10, and write the final answer in scientific notation.

Step-by-step explanation:

The expression that makes the equation true is (9.109) · (–2.10⁻³) = 5.0 × 10⁻⁹.

To solve this, multiply the two numbers together:

• Multiply 9.109 by -2 to get -18.218.
• Add the exponents of 10, which gives us -3 + (-³) = -6.
• Write the final answer in scientific notation, giving us 5.0 × 10⁻⁹.
