Frequently Asked Questions
What is an exponent?
An exponent tells you how many times to multiply a base by itself. 2Β³ = 2 Γ 2 Γ 2 = 8.
What is any number to the power of 0?
Any non-zero number raised to the power of 0 equals 1. For example, 5β° = 1.
What about negative exponents?
A negative exponent means divide by that power. 2β»Β³ = 1/2Β³ = 1/8 = 0.125.
What is a fractional exponent?
Fractional exponents are roots. x^(1/2) is square root, x^(1/3) is cube root.
