1) (7×9) + (7×11) =7× (9+11)
= 7×20
=140 Menggunakan Sifat Distributif

2) 4×21×75=4×75×21
=300×21
=6300 Menggunakan Sifat Asosiatif

8×57=8× (60-3)
= (8×60)- (8×(-3))
=480-(-24)
=504 Menggunakan Sifat Distributif

Answer 2

1.(7×9) + (7×11) =7× (9+11)
= 7×20
=140

2.4×21×75=4×75×21
=300×21
=6300

3. 8×57=8× (60-3)
= (8×60)- (8×(-3))
=480-(-24)
=504
Maaf kalau salah
