WebWhen the number has a negative exponent, you put that number at the denominator. For example, 1^-1 will be 1/1^1. The exponent is now positive because it was moved down to the denominator. Same thing if there is a negative power on the bottom of the fraction. 1/2^-2 is 4. 2^2 is 4, but the power is negative so I had to move it to the top. WebThe exponent of a number says how many times to use the number in a multiplication. In 82 the "2" says to use 8 twice in a multiplication, so 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared". Some more examples:

WebJan 31, 2024 · Here's a good heuristic that helped me feel better about it back in the day: Consider any number x to any power. We will choose, say, 5 3. 5 3 = 125. Divide both sides by 5. You get 5 2 = 25, which we know. Again. Then you get 5 1 = 5. We usually leave exponents of 1 off but we'll keep it here.
