Formula
b^m ×b^n=b^(m+n).
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Integer exponents, strictly positive base. Floating-point output.
Example Calculation
Example inputs
- Positive base: 2
- First exponent: 3
- Second exponent: 4
Positive base = 2; First exponent = 3; Second exponent = 4. Primary result: 128.
Frequently asked questions
How do I use this calculator?
Enter positive base, first exponent, second exponent. The result updates automatically. Use Reset to restore the example values.
What method does it use?
b^m ×b^n=b^(m+n).. Integer exponents, strictly positive base. Floating-point output.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
