Working with very large or very small numbers can be challenging in mathematics, science, and engineering. Exponential notation (also called scientific notation) makes it easier to express numbers in a compact form, using powers of ten.
Exponential Notation Calculator
Exponential notation expresses numbers as a base number multiplied by ten raised to an exponent. It is particularly useful for representing extremely large or small numbers without writing many zeros.
General Form:
N = a × 10^b
Where:
- a = Base number (between 1 and 10)
- b = Exponent (positive for large numbers, negative for small numbers)
Example:
- 5,000 = 5 × 10³
- 0.00032 = 3.2 × 10⁻⁴
Exponential notation is commonly used in physics, chemistry, finance, computer science, and engineering to simplify calculations and maintain precision.
