Answer 1

8 nhé k nha

Answer 2

. 72^3 * 54^2 / 108^4 
= 72^3 * 54^2 / (2 * 54)^4 
= 72^3 * 54^2 / 2^4 * 54^4 
= 72^3 * 54^2 / 2^4 * 54^2 * 54^2 
= 72^3 / 2^4 * 54^2 
= 72^3 / (2^2)^2 * 54^2 
= (9 * 8)^3 / 4^2 * (9 * 6)^2 
= 9^3 * 8^3 / 4^2 * 9^2 * 6^2 
= 9 * 9^2 * (4 * 2)^3 / 4^2 * 9^2 * 6^2 
= 9 * 4^3 * 2^3 / 4^2 * 6^2 
= 9 * 4 * 4^2 * 8 / 4^2 * 36 
= 9 * 4 * 8 / 36 
= 36 * 8 / 36 
= 8
