Exponentiation operator uses a double asterisk: 2**5 == 32 0**1 == 0 0**0 == 1

Yes, it depends on implementation of the exponentiation operator - which rule fires off first - 0**x == 0 or x**0 == 1 :) Other languages might have other results.

Angelo B. You are right, there is no universally accepted definition for 0**0. Kuba summed up the reason succinctly: while "anything" to the power of zero is 1, zero to the power of "anything" is zero. However, it is sometimes defined as 1 in some branches of mathematics (like algebra, set theory, and combinatorics) for the sake of convenience.

Thanks to all but, if you try in programming languages 0/0, that is an indeterminate form, the result is an error or NAN. I think the result =1 only for convention, infact all calculators give 1 as result, but strictly math speaking, this is not the true

In math 0**0 Is indefinite form, not 1. Strange result

iirc anything to the power of 0 is 1, and 0 itself isn't exempt from this. kinda like how 0! is 1, it just works. Angelo B.

maybe using numpy the result is correct.

angelo B. 0**0 is 1 becase 0**0 means nothing at all but there must be something.so it becomes 1*0**0 which is 1
