Wrong answers / wrong calculations in math operations in Chat GPT

[brisk sparrow]

There are errors in calculations in ChatGPT.
For example, ChatGPT calculations of the time that the black hole takes to dissipate are completely wrong. For a black hole with mass of 10^6 kg ChatGPT result is:
t ≈ 2.097 x 10^67 seconds
But correct result is:
t ≈ 84,1 seconds
Moreover ChatGPT can’t even calculate correctly the value of
hbar x c^4
where:
hbar = reduced Planck constant
c = speed of light
ChatGPT result is:
hbar x c^4 ≈ 1.956 x 10^-7 J m^4/s^4
But correct result is:
hbar x c^4 ≈ 0,851841836 J m^4/s^3
In such calculations ChatGPT results are completely wrong all the time.
