why why why why ??
Can you explain me why 0^0=1 but 0^1=0 ??

Dragonfall said:0^0 is undefined. It's not equal to 1.
g_edgar said:On the other hand, for cardinal numbers, say 0, we get 0^0 = 1 since there is exactly one function from the empty set to itself.
Dragonfall said:There is no function from the empty set to itself, if we don't allow the empty set to be a function.
Dragonfall said:Calculator is wrong. Well, it's not completely right. 0^0 is undefined in general, and in very specific cases which people have pointed out, it may be 0 or 1 or whatever.

can you explain me
In lots of places in math we say 0^0=1 as abuse of notation. It is a very convenient abuse of notation, but abuse nonetheless. For example, this abuse of notation let's us write infinite series in the formJCVD said:in discrete math we like to say 0^0=1 ...
Whatever123 said:You can think of it as a division by zero, which is why it doesn't work... x^n/x^m = x^(n-m). Therefore, 0^0 = 0^x/0^x, which is, of course, 0/0 and in the indeterminate form...

CR, can you explain that second result, %2=2?? Not the %2, I understand that. The right hand side, =2.CRGreathouse said:Here's Pari's opinion:
Code:> 0^0 %1 = 1 > 0.0^0 %2 = 2 > 0^0.0 *** _^_: gpow: 0 to a non positive exponent. > 0.0^0.0 *** _^_: gpow: 0 to a non positive exponent.
0^0 and 0^1 are mathematical expressions representing the powers of 0. 0^0 is often considered an indeterminate form, while 0^1 is equal to 0.
0^0 is considered an indeterminate form because it can take on different values depending on the mathematical context. In some cases, it may be equal to 1, while in others it may be undefined or equal to 0.
No, 0^0 cannot be defined as a specific value because it can take on different values depending on the context. It is often best to leave it as an indeterminate form.
The value of 0^1 is determined by the exponent rule, which states that any number raised to the power of 1 is equal to that number. In this case, 0^1 is equal to 0.
The practical applications of understanding 0^0 and 0^1 include solving certain mathematical problems and equations, such as limits in calculus and combinatorics. It also helps to understand the concept of indeterminate forms and how they can be used in various mathematical contexts.
