How It Works
Base^Exponent means multiplying the base by itself exponent times. 2^10 = 2Γ2Γ2Γ2Γ2Γ2Γ2Γ2Γ2Γ2 = 1,024. A negative exponent means 1 divided by the positive power.
Example
2^10 = 1,024. 10^3 = 1,000. 2^-3 = 0.125. 1.05^20 = 2.6533 (compound growth at 5% for 20 years).
Frequently Asked Questions
What is a negative exponent?
A negative exponent means the reciprocal: x^-n = 1/x^n. So 2^-3 = 1/2^3 = 1/8 = 0.125.
What does x^0 equal?
Any nonzero number raised to the power of 0 equals 1. This is a fundamental rule of exponents.
What is scientific notation?
A way to write very large or small numbers using powers of 10. 3.5 Γ 10^6 = 3,500,000. Useful in science and engineering.
