Formula & Methodology
The scientific notation for a number represents it in the form of a number between 1 and 10 multiplied by a power of 10. The formula for multiplying two numbers in scientific notation is:
(a × 10^m) × (b × 10^n) = (a × b) × 10^(m + n)
Real-World Examples
Example 1
Multiply 3.4 × 10^5 by 2.7 × 10^3.
Solution: (3.4 × 10^5) × (2.7 × 10^3) = (3.4 × 2.7) × 10^(5 + 3) = 9.18 × 10^8
Example 2
Multiply 6.5 × 10^2 by 4.3 × 10^4.
Solution: (6.5 × 10^2) × (4.3 × 10^4) = (6.5 × 4.3) × 10^(2 + 4) = 27.85 × 10^6
Example 3
Multiply 9.2 × 10^3 by 1.8 × 10^2.
Solution: (9.2 × 10^3) × (1.8 × 10^2) = (9.2 × 1.8) × 10^(3 + 2) = 16.56 × 10^5
