1E3×100

1E3×100, also known as 1.3 x 10^3 * 100, is a mathematical expression that simplifies to 1300. The notation "1E3" is a common way to represent scientific notation, specifically 1.3 multiplied by 10 raised to the power of 3, which equals 1300. Multiplying this value by 100 results in 130,000. Alternatively, if "1E3" is interpreted as 1 x 10^3, then the expression becomes 1000 multiplied by 100, resulting in 100,000. The ambiguity lies in whether the "1" preceding the "E3" is a standalone digit or part of the mantissa in scientific notation. In standard scientific notation, the mantissa is typically expressed with a decimal point, such as 1.3E3. Without explicit clarification, the interpretation of "1E3" as 1.3 x 10^3 is common in many computational contexts. Therefore, 1E3×100 most frequently evaluates to 130,000.
