The exponent $0$ provides $0$ power (i.e. gives no power of transformation), so $3^0$ gives no power of transformation to the number $1$, so $3^0=1$. Once you have the intuitive understanding, you can use the simple rules with confidence.

6 cze 2021 · 😉 In this exponents tutorial I explain why any number to the power of 0 (zero power) always equals 1. I provide Illustrations that explain the zero exponent rule. I also explain what a...
28 lip 2023 · If we start only with \(a^1=a\) and the product rule, then we can immediately prove that \(a^0=1\) because \(a^0\cdot a=a^0\cdot a^1=a^{0+1}=a^1=a\), and dividing through by a (which is assumed not to be zero), we conclude that \(a^0=1\). But then for any positive integer n, $$a^n=a^{\overset{n\text{ times}}{\overbrace{1+1+\cdots+1}}}=\overset ...
18 lut 2016 · So what does zero to the zero power equal? This is highly debated. Some believe it should be defined as 1 while others think it is 0, and some believe it is undefined.
Strictly speaking we say $0^{-1}$ is undefined. $x^{-1}$ is the multiplicative inverse of the number $x$. By definition of the multiplicative inverse, the product of a number and its multiplicative inverse equals one. So we would have $0\times 0^{-1} = 1$.
31 sty 2017 · $$0 + 2 + 2 + 2 = 2 \times 3$$ In this form certain behaviors become quite clear: Negatives also make sense, because instead of adding numbers, you do the opposite, you un-add (often called "subtraction"):
In other words, if you raise a nonzero number to the power of 0, the result is 1. Mathematicians debate the value of 00. Some say it's 1, and some say it's undefined. Here are some examples of the Zero Power Rule. Notice it works for numbers and for variables. 10=1 (153+x)0=1, if x≠−153 (x+y+z)0=1, if x+y+z≠0. So when a≠0, why does a0=1?
