Formula Explained
When multiplying numbers in scientific notation, you multiply the coefficients and add the exponents:
(a × 10b) × (c × 10d) = (a × c) × 10b+d
For example, multiplying 1.47 × 10³ and 0.860 × 10²:
- Multiply the coefficients: 1.47 × 0.860 = 1.2642
- Add the exponents: 3 + 2 = 5
- Combine to get 1.2642 × 10⁵
This is equivalent to 126,420 in standard form.
Worked Examples
Example 1: Basic Multiplication
Calculate 1.47 × 10³ × 0.860 × 10²:
- Multiply coefficients: 1.47 × 0.860 = 1.2642
- Add exponents: 3 + 2 = 5
- Result: 1.2642 × 10⁵ (or 126,420)
Example 2: Different Exponents
Calculate 2.5 × 10⁴ × 3.1 × 10⁻²:
- Multiply coefficients: 2.5 × 3.1 = 7.75
- Add exponents: 4 + (-2) = 2
- Result: 7.75 × 10² (or 775)
Frequently Asked Questions
What is scientific notation?
Scientific notation is a way of writing very large or very small numbers by expressing them as a product of a number between 1 and 10 and a power of 10. For example, 1,470,000 is written as 1.47 × 10⁶.
How do I multiply numbers in scientific notation?
To multiply numbers in scientific notation, multiply the coefficients and add the exponents. For example, (2 × 10³) × (3 × 10⁴) = (2 × 3) × 10³⁺⁴ = 6 × 10⁷.
What if one of the coefficients is less than 1?
If one of the coefficients is less than 1 (like 0.860), you can still multiply it normally. The result will automatically be in proper scientific notation. For example, 1.47 × 0.860 = 1.2642.
