24¹⁸=(2³x3)¹⁸=2⁵⁴x3¹⁸
64⁹=(2⁶)⁹=2⁵⁴
100⁹=(2²x5²)⁹=2¹⁸x5¹⁸
64³=(2⁶)³=2¹⁸
3375⁴⁷=(5³x3³)⁴⁷=5¹⁴¹x3¹⁴¹
[(2⁵⁴x3¹⁸:2⁵⁴)x(2¹⁸x5¹⁸:2¹⁸)]⁸:5¹⁴¹x3¹⁴¹=
[(2⁵⁴⁻⁵⁴x3¹⁸)x(2¹⁸⁻¹⁸x5¹⁸)]⁸:5¹⁴¹x3¹⁴¹=
[2°x3¹⁸x2°x5¹⁸]⁸:5¹⁴¹x3¹⁴¹=
[3¹⁴⁴x5¹⁴⁴]:5¹⁴¹x3¹⁴¹=
3¹⁴⁴⁻¹⁴¹x5¹⁴⁴⁻¹⁴¹=3³x5³=15³

[(2^54.3^18:2^54)x(2^18.5^18:2^18)]^8:3^141.5^141=
(3^18.5^18)^8:(3.5)^141=
(3.5)^144:(3.5)^141=(3.5)³=15³=3375
