43*42+57*43+43
= 43 * ( 42 + 57 + 1)
= 43 * 100
= 4300
43 x 42 + 57 x 43 + 43 = 43 x (42 + 57 + 1) = 43 x 100 = 4300 (k cho tớ với nhá!)
43 x 42 + 57 x 43 + 43 = 1806 + 2451 + 43
= 4300
Nhớ click cho mik nha !!!!!!!!!!!!!!!!
43x42+57x43+43
=43x42+57x43+43x1
=(42+57+1)x42
=100x42
=4200
Nhớ k mình nha
43 x 42 + 57 x 43 + 43
= 43 x 42 + 57 x 43 + 43
= 43 x [ 42 + 57 + 1 ]
= 43 x 100
= 4300
43x42+57x43+43=43x(42+57+1)
=43x100
=4300
43x42+57x43+43
=43x42+57x43+43x1
=(42+57+1)x42
=100x42
=4200
43 x 42 + 57 x 53 + 43
= 43 x 42 + 57 x 43 + 43
= 43 x ( 42 + 57 + 1 )
= 43 x 100
= 4300
43 x 42 + 57 x 43 + 43
= 43 x 42 + 43 x 57 + 43 x 1
= 43 x ( 42 + 57 + 1 )
= 43 x 100
= 4300
