Exponent Calculator
Formula
result = base ^ exponent
Raising a number to a power means multiplying it by itself that many times. 2^10 = 2×2×2×2×2×2×2×2×2×2 = 1024.
How to use
- Enter the Base number.
- Enter the Exponent (the power to raise it to).
- Read the Result of the calculation.
Example
2 raised to the 10th power means multiplying 2 by itself 10 times: 2^10 = 1,024. Larger exponents grow the result very quickly.
Frequently Asked Questions
What is 2^10?
2^10 = 1,024.
What is any number to the power of 0?
Any non-zero number raised to the power of 0 equals 1.
What does a fractional exponent like 2^0.5 mean?
A fractional exponent represents a root: raising a number to the power of 0.5 is the same as taking its square root, so 2^0.5 is about 1.414. More generally, the denominator of the fraction tells you which root to take, so 8^(1/3) is the cube root of 8, which is 2. This is why exponents and roots are really two sides of the same operation.
What's the difference between 2^3 and 3^2?
Exponentiation is not commutative, so the order matters: 2^3 means 2 multiplied by itself 3 times, which equals 8, while 3^2 means 3 multiplied by itself 2 times, which equals 9. They happen to be close here, but the gap grows quickly with larger numbers. Always read the base as the number being multiplied and the exponent as how many times.
