1. 71 - 37 + 15 x 60 : 2 = 2. -1200 + (-275 : 25) x (-30) = 3. 1/2 x 3/4 : 3/8 = 4. FPB 48 dan 80 = 5. KPK 56 ,72 ,84 = Tolong pake cara

1. 71-37+(15x60):2
71-37+(900:2)
71-37+450
34+450=484
2. -1200+(-11)x(-30)
-1200+330
=-870
4. 48=2⁴x3
80=2⁴x5
FPB=2⁴=16
5. 56=2³x7
72=2³x3²
84=2²x3x7
KPK=2³X3²X7=8x9x7=72x7=504

Jawabannya:
2. -1200+(-11)×(-30)
= -1200+330
= -870
4. 48=2^4×3
80=2^4×5
Fpb= 2^4=16
5. 56=2^3×7
72=2^3×3^2
84=2^2×3×7
Kpk= 2^3×3^2×7
= 8×9×7
= 72×7
= 504
