1) -25 × ( -8) - 50 + 5
= 200 - 50 + 5
= 150 + 5
= 155 ( C )

2) ( 25 × 6.500 ) - ( 15 × 6.200)
= 162.500 - 93.000
= 69.500 ( B )

3) 24 = 2³ × 3
36 = 2² × 3²
fpb = 2² × 3 = 12 ( A )

4) 21 = 3 × 7
35 = 5 × 7
kpk = 3 × 5 × 7 = 105 ( C )

5) 140 = 2² × 5 × 7
150 = 2 × 3 × 5²
kpk = 2² × 3 × 5² × 7 = 2.100 km ( B )

6) 12³ + 20³
= 1.728 + 8.000
= 9.728 ( C )

7) ³√216 × ³√512
= 6 × 8
= 48 ( C )
