How it works
Raising a number to a positive whole power means multiplying it by itself that many times. Two to the power of three is two times two times two.
A negative exponent means one divided by the number raised to the positive exponent. An exponent of one half means the square root.
Worked example
2 raised to the power of 10 is 1,024.
Questions
What is a number to the power of zero?
Any number except zero itself, raised to the power of zero, is one.
Can the exponent be a decimal?
Yes. A decimal exponent gives a root or a value in between, such as 0.5 for a square root.
What happens with a negative base?
A whole-number exponent works fine. A fractional exponent on a negative base often has no ordinary answer, so check the result carefully.
