(1.25 × 10-5) × (3.50 × 105)
(1.25 × 10-5) × (3.50 × 105) = 4.375 × 100
= 4.375 × 10^2
To multiply these two numbers in scientific notation, you need to multiply the decimal parts (1.25 × 10^-5) and (3.50 × 10^5), and then multiply their exponential parts.
First, multiply the decimal parts:
1.25 × 3.50 = 4.375
Next, multiply the exponential parts:
10^(-5) × 10^5 = 10^(-5+5) = 10^0 = 1
Finally, combine the results:
4.375 × 1 = 4.375
Therefore, the result of (1.25 × 10^(-5)) × (3.50 × 10^5) is 4.375.
