Multiplying Numbers in Scientific Notation: A Step-by-Step Guide
Scientific notation is a way to express very large or very small numbers concisely. Let's explore how to multiply numbers in scientific notation, specifically: (1.7 x 10<sup>4</sup>) x (8.5 x 10<sup>-2</sup>)
Step 1: Multiply the Coefficients
First, multiply the coefficients, which are the numbers in front of the powers of ten.
- 1.7 x 8.5 = 14.45
Step 2: Multiply the Powers of Ten
Next, multiply the powers of ten by adding their exponents.
- 10<sup>4</sup> x 10<sup>-2</sup> = 10<sup>(4 + (-2))</sup> = 10<sup>2</sup>
Step 3: Combine the Results
Combine the results of step 1 and step 2 to get the final answer in scientific notation.
- 14.45 x 10<sup>2</sup>
Step 4: Adjust for Standard Form
To express the answer in standard form, we need to ensure the coefficient is between 1 and 10. Move the decimal point one place to the left and increase the exponent by one.
- 1.445 x 10<sup>3</sup>
Therefore, the product of (1.7 x 10<sup>4</sup>) x (8.5 x 10<sup>-2</sup>) in standard form is 1.445 x 10<sup>3</sup>.
