(1): "^-2" was replaced by "^(-2)".

Step  1  :

 1.1     8 = 23

(8)⁵ = (2³)⁵ = 2¹⁵

Equation at the end of step  1  :

  (8-2) • (215^6)
 Step  2  :
 2.1     8 = 23

(8)^-2 = (2³)^(-2) = (2)^(-6)

Equation at the end of step  2  :

  (2)(-6) • 290

Step  3  :

Dividing exponents :

 3.1    2⁹⁰   divided by   2⁶   = 2^{(90 - 6)} = 2⁸⁴

Final result :

  284
