tolong jawab ya no. 1 sampai 5 aja

1) 600 : 120 + 37 - 42 x (-12)
= (600 : 120) + 37 - (42 x -12)
= 5 + 37 - (-504)
= 5 + 37 + 504
= 546

2) 6464 : 16 - 625 : (-25)
= (6464 : 16) - (625 : -25)
= 404 - (-25)
= 404 + 25
= 429

3) -78 + [ (6 x 9) + 42]
= -78 + [54 + 42]
= -78 + 96
= 18

no 4 dan 5 di foto ya (capek ngetik wkwk)

1.600:120+37-42×(-12)=5+37-(-504)=42+504=546
2.646:16-625:(-25)=404-1=403
3.-78+[(6×9)+42]=-78+(36+42)=-78+78=0
4.105-(-5)×9:(-3)=105+5×(-3)=105+(-15)=90
5.246:(-6)+38×4-126= -41+152-126=111-126= -15
