33 . 45 + 67 . 45 = 1485 + 3015 =4500
\(33.45+67.45\)
\(=45.\left(33+67\right)\)
\(=45.100\)
\(=4500\)
k mình nha
33 . 45 + 67 .45 = ( 33 + 67 ) . 45
= 100 . 45 = 4500
\(33.45+67.45\)
= \(45.\left(33+67\right)\)
= \(45.100\)
=\(4500\)
Chúc bạn học tốt !!!
33 . 45 + 67 . 45
= 45 ( 33 + 67 )
= 45 . 100
= 4 500
=))
33 . 45 + 67 . 45
= ( 33 + 67 ) . 45
= 100 . 45
= 4500
33 . 45 + 67 . 45
=45(33+67)
=45.100
=4500
33.45+67.45
=45.(33+67)
=45.100
=4500
HOK TỐT
