(30^2 . 4^2 . 25) : (2^3 . 5^2)
= (30^2 . 4^2 . 5^2) : (2^2 . 2 . 5^2)
= (30 . 4 . 5)^2 : [(2 . 5)^2 . 2]
= 600^2 : [10^2 . 2]
= (600^2 : 10^2) . 2
= 60^2 . 2
= 3600 . 2
= 7200.

\(\left(30^2.4^2.25\right):\left(2^3.5^2\right)\)
\(=30^2.4^2.5^2:2^3:5^2\)
\(=\left(30.4.5:5\right)^2:2^3\)

Kết quả của (30^2 . 4^2 . 25) : ( 2^3 . 5^2) =1800
Cậu nhớ đánh dấu cho mình nhá
42 = 24 ; 25 = 52 => (42.25 ) : (23 .52) =2
302.2 = 1800
Ta có :
( 302 . 42 . 25 ) : ( 23 . 52 )
= ( 900 . 16 . 25 ) : ( 8 . 25 )
= ( 900 . 2 . 8 . 25 ) : ( 8 . 25 )
= 900 . 2
= 1800
