jawablah dengan benar 1sampai 6

1) b 71
2) a 160
3) c 230
4 )c 6
5) b 16

1. 15 + 7 x 8 =
= 15 + 56
= 71

2. (23+17) x (24:6) =
= 40 x 4
= 160

3. 144 + 32 x 45 : 15 - 10 =
= 144 + 1.380 : 15 - 10
= 144 + 92 - 10
= 236 - 10
= 226

4. 35 = 5 x 7
42 = 2 x 3 x 7
56 = 2³ x 7
FPB = 7

5. 65 = 5 x 13
78 = 2 x 3 x 13
104 = 2³ x 13
FPB = 13

6. 40 = 2³ x 5
50 = 2 x 5²
60 = 2² x 3 x 5
FPB = 2 x 5
= 10

Maaf klo salah
