[@LePhenixGD]

You should try using forbidden logarithm bases such as negative numbers, 0 and 1 on calculators For example: log₁(420) or log₀(69)

[@NikoCubeRoot]

Logarithm of one? Division by zero?? Infinity?!?

[@hmwndp]

log_x y = ln(y)/ln(x). So log₁ n = ln(n)/0, because log_x 1 = 0 for any x. Thus it must follow that log₁ is undefined. log₀ n = ln(n)/ln(0), log_x 0 has no answer for any x. Thus it must follow that log₀ is too undefined. log_(−a) n = ln(n)/ln(−a). log_x (−a) has no answer for any x, in the real number system. Thus it must follow that log_(−a) is, yet again, undefined. By the statements above, it is concluded that these logarithm bases are impossible for any calculator to compute.

[@allama.9571]

I actually tried log_1 (which is the equivalent of dividing by zero) on the Windows calculator and found that log_1(1) gives the same message as 0/0 (as it is log(1)/log(1) = 0/0), and log_1 of any other number gives the same message as a nonzero number divided by zero.

[@MuffinsAPlenty]

I have a request, if you're willing. What happens if you input 2^2^3 on different calculators? I know that some calculators treat exponentiation as right-associative (which yields an answer of 256) and some treat it as left-associative (which yields an answer of 64), and it would be interesting to see which calculators do which.

[@ondrejpavlik4210]

@World of OSes Speaking of logarthms on calculators, could you do the same thing with base 1 logarithm?

[@hmwndp]

log₁ n is undefined. Why? The reasons are: log_x y = ln(y)/ln(x). log₁ n = ln(n)/ln(1) = ln(n)/0. (log_x 1 = 0 for any x) Division by zero is not defined, thus it must follow that log₁ n is also undefined.

[@ratishone1]

The logarithm of 0 to any base is undefined. This is because of the logarithm is the inverse of exponentiation, and there is no real number n in which 10^n = 0. This is because of 10 to any negative power is a positive fraction, so the limit of log base 10 n as n reaches zero from positive side is -∞

idea: (-1)^(2/3) and (-1)^(3/4) in different calculators These two are interesting because first one has 2 complex and 1 real values, second one has 4 complex values. Will calc show all values? Will prefer real value over complex ones?

-infinity/-infinity is 1

[@0LoneTech]

​@@Austinkeith2010Only if you know the two infinities are identical. Normally this is lost context, as e.g. 2×infinity and 3×infinity are both infinity, so infinity/infinity is undefined (as likely to be 2/3 as 3/2, 0 or infinity). Such undeterminable relations lead e.g. to Qalculate's nonsensical answer: log(0, 0) = (−∞) × 0
