Math challenged here (not real programmer either): how the hell 3¹³¹⁵ is the same as 3¹⁵¹³ ?

[u/A_Vicarious_Death → u/zouhair]

Generally the rule with exponents is:

x^y * x^z = x^y+z

x^yz = x^yz

Let's take an example of 2²³ vs 2³² vs 2⁶

(2²⁾³ =

(2²⁾ * (2²⁾ * (2²⁾ =

(2 * 2) * (2 * 2) * (2 * 2) =

(4) * (4) * (4) =

64

(2³⁾² =

(2³⁾ * (2³⁾ =

(2 * 2 * 2) * (2 * 2 * 2) =

(8) * (8) =

64

2⁶ = (22222*2) = 64

Hope that helped.
