Solution - Raising to a power

Step  1  :

 1.1     9 = 32

(9)⁴ = (3²)⁴ = 3⁸

Equation at the end of step  1  :

  (((62) +  38) -  10)0

Step  2  :

 2.1     6 = 2•3

(6)² = (2•3)² = 2² • 3²

Equation at the end of step  2  :

  (((22•32) +  38) -  10)0

Step  3  :

 3.1     Anything raised to the zeroth power is 1. On the other hand, zero raised to any power is 0. What if zero is raised to the zeroth power ?

Well, some authors define 0^0 = 1, whereas others leave it undefined. Tiger shall regard it as 1

Final result :

  1
