WebIf S = 0.999…, then 10*S = 9.999… so by subtracting the first equation from the second, we get. 9*S = 9.000…. and therefore S=1. Here’s another argument. The number 0.1111… = 1/9, so if we multiply both sides by 9, we obtain 0.9999…=1. You might also mention that by similar arguments, every rational number with a terminating decimal ... WebAnswer: As already explained, the answer to (-1)0 is 1 since we are raising the number -1 (negative 1) to the power zero. However, in the case of -10, the negative sign does not …

WebYes, at any given stop, at any given stage of the expansion, for any given finite number of 9 s, there will be a difference between 0.999...9 and 1. That is, if you do the subtraction, 1 − 0.999...9 will not equal zero. But the point of the "dot, dot, dot" is that there is no end to the 9 s; 0.9999... is inifinte. There is no "last" digit.

Actually, it is related. Proving that inverses are unique implies that as long as 0 is an inverse of 0, it is the unique inverse of 0.

exponentiation - Why is $n^0 = 1$? - Mathematics Stack Exchange
WebApr 29, 2015 · 0 The way I think about this (which may or may not be write) is that exponentiation (by integers) is viewed as a n = 1 ⋅ a ⋅ a ⋅... ⋅ a where there are n copies of a. If n = 0, then there is only the 1. You could also view a n as a n = ∏ i = 1 n a. Then, just note that the empty product is 1 ... unlike the empty sum which is 0.
