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...
18 lut 2016 · Raise a number to the power of 1 means you have one of that number, raise to the power of 2 means you have two of the number multiplied together, power 3 means three of the number...
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, $$a^n=a^{\overset{n\text{ times}}{\overbrace{1+1+\cdots+1}}}=\overset ...
The definition $\ 2^0 = 1\ $ is "natural" since it makes the arithmetic of exponents have the same structure as $\mathbb N$ (or $\mathbb Z\:$ if you extend to negative exponents).
31 sty 2017 · $$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"):
What is the difference between -1 to the zero power and (-1) to the zero power? Will the answer be 1 for both? Example 1: -1 0 = ____ Example 2: (-1) 0 = ___ Answer: As already explained, the answer to (-1) 0 is 1 since we are raising the number -1 (negative 1) to the power zero.
