Question

(3*(-2))*5=? (-9*4)*(-2,5)=? (13*(-5))*20=? (-9*15)*(-2)=? (-8*(-12))*5=? (3*(-25))*2=?

Answer 1

1)=-6*5=-30

2)=-36*(-2,5)=90

3)=-65*20=-1300

4)=-135*(-2)=270

5)=96*5=480

6)=-75*2=-150

Answer 2

To calculate the given expressions, let's solve each one step by step:

1. (3 * (-2)) * 5 First, multiply 3 by -2, which gives you -6. Then, multiply -6 by 5. (-6) * 5 = -30

2. (-9 * 4) * (-2.5) First, multiply -9 by 4, which gives you -36. Then, multiply -36 by -2.5. (-36) * (-2.5) = 90

3. (13 * (-5)) * 20 First, multiply 13 by -5, which gives you -65. Then, multiply -65 by 20. (-65) * 20 = -1300

4. (-9 * 15) * (-2) First, multiply -9 by 15, which gives you -135. Then, multiply -135 by -2. (-135) * (-2) = 270

5. (-8 * (-12)) * 5 First, multiply -8 by -12, which gives you 96. Then, multiply 96 by 5. 96 * 5 = 480

6. (3 * (-25)) * 2 First, multiply 3 by -25, which gives you -75. Then, multiply -75 by 2. (-75) * 2 = -150

Therefore, the results are:

1. (3 * (-2)) * 5 = -30
2. (-9 * 4) * (-2.5) = 90
3. (13 * (-5)) * 20 = -1300
4. (-9 * 15) * (-2) = 270
5. (-8 * (-12)) * 5 = 480
6. (3 * (-25)) * 2 = -150
