25x(5-2) divided 5-12+24 divided by 2 to the 3rd power +6+2 to the 4th power divided by 4-(1+3)+
(4 the 3rd power-20x3)-4 to the second power+3 to the 5th power divided by 3 divided by (10-1)-8.

[25 x (5-2)] / [5 - 12 + 24] / [ 2³ + 6 + 2^4] / [4-(1+3) + (4³ - 20 x 3) - 4² + 3^5] / [3] / [(10-1) - 8]

= [25 x (5-2)] / [5 - 12 + 24] / [8+ 6 + 16] / [4 - (1+3) + (64 - 20 x 3) - 16 + 243] / [3] / [(10-1) - 8]

= [25 x 3] / [5 - 12 + 24] / [8 + 6 + 16] / [4 - 4 + 4 - 16 + 243] / [3] / [9 - 8]

= 75 / 17 / 30 / 231 / 3 / 1

= 0.000212206094599
