Answer 1

a) (+20).(-5)= - (20 × 5) => -100

b) (-6).(-11).(35)= 6 × 11 × 35 => 210 × 11 => 2310

c) (+15).(-4).(-5).(+2)= 15 × 4 × 5 × 2 => 15 × 4 × 10 => 150 × 4 => 600

d)(-3).(-3).(-3).(-3).(-3)= - (3 × 3 × 3 × 3 × 3) => -243

e) (-10).(-2).(-5).(-13)= 10 × 2 × 5 × 13 => 10 × 10 × 13 => 10² × 13 => 100 × 13 => 1300

Bons estudos!!
