22344 x 36 + 44688 x 82

= 22344 x 36 + 22344 x 2 x 82

= 22344 x ( 36 + 82 x2)

= 22344 x 200

= 4468800

Số bé nhất chia hết cho 4 là : 104

Số lớn nhất chia hết cho 4 là : 296

Số các số là :

( 296 - 104 ) : 4 + 1 = 49 ( số ) nke

[ 3 x ( x + 2 ) : 7 ] x 4 = 120

[ 3 x ( x + 2 ) : 7 ] = 120 : 4

[ 3 x ( x + 2 ) : 7 ] = 30

[ 3 x ( x + 2 ) ] = 30 x 7

[ 3 x ( x + 2 ) ] = 210

[ ( x + 2 ) ] = 210 : 3

[ ( x + 2 ) ] = 70

x = 70 - 2

x= 68

\(\frac{9^5.16^4}{27^3.8^4}=\frac{\left(3^2\right)^5.\left(2^4\right)^4}{\left(3^3\right)^3.\left(2^3\right)^4}=3.2^4=3.16=48\)
