eπ i = -1

Properties : abc = (ab)c

(eπ )i = -1

Calculating eπ, we get:

(23.1406926328)i = -1

i√ on both sides, we get:

23.1406926328 = i√ i5

23.1406926328 = i5 / i

23.1406926328 = i-5 i

Calculate the reciprocals. Properties: 1 / x for x = 22 = 1 / 4 = 2-2.

1 / 23.1406926328 = i5 i 

 

0.04321391827 = i5 i

 

0.043213918271 / 5i = i

 

0.043213918272 / 5i = -1

 

 

Is this factually correct? I'm not sure...

Hi MWizzard :)

 

You lost me here

 

23.1406926328 = i√ i5

you wanted

\(\sqrt[i]{-1}=\ {(-1)}^{1/i}\\ Where\; did\; your\; i^5 \;come\; from?\;\;i^5=i \;\;but\;so\;what?\)

 

I might be missing something ://

sum_(n=0)^99 ((-1)^n (pi*i)^n)/n!)~ -1.0000000000000000000000000000000000000000+0.×10^-40 i

As with melody, I'm not sure where your gettin the exponent 5 from. However, I've checked and double checked the math and looked around for another answer online and you aren't the first to notice this, but yes, you're factually correct according to the internet.
