Answer

Explanation:

Step1: Multiply the numbers

For (5(-2)), multiply (5) and (-2). (5\times(-2)=-(5\times2)= - 10)

Step2: Multiply the numbers

For (6(-4)), multiply (6) and (-4). (6\times(-4)=-(6\times4)=-24)

Step3: Multiply the numbers

For (4(21)), multiply (4) and (21). (4\times21 = 84)

Step4: Multiply the numbers

For (-11(-5)), multiply (-11) and (-5). ((-11)\times(-5)=11\times5 = 55)

Step5: Multiply the numbers

For (-6(5)), multiply (-6) and (5). ((-6)\times5=-(6\times5)=-30)

Step6: Multiply the numbers

For (-50(0)), multiply (-50) and (0). ((-50)\times0 = 0)

Step7: Multiply the numbers

For (-5(-5)), multiply (-5) and (-5). ((-5)\times(-5)=5\times5 = 25)

Step8: Multiply the numbers

For (-4(8)), multiply (-4) and (8). ((-4)\times8=-(4\times8)=-32)

Step9: Calculate the power

For ((-6)^{2}), ((-6)^{2}=(-6)\times(-6)=36)

Step10: Calculate the power

For ((-2)^{2}), ((-2)^{2}=(-2)\times(-2)=4)

Step11: Calculate the power

For ((-4)^{3}), ((-4)^{3}=(-4)\times(-4)\times(-4)=-(4\times4\times4)=-64)

Step12: Calculate the power

For ((-5)^{3}), ((-5)^{3}=(-5)\times(-5)\times(-5)=-(5\times5\times5)=-125)

Step13: Substitute and calculate

For (-2d) with (d = 4), (-2d=-2\times4=-8)

Step14: Substitute and calculate

For (6a) with (a=-5), (6a=6\times(-5)=-30)

Step15: Substitute and calculate

For (3ab) with (a = - 5) and (b = 2), (3ab=3\times(-5)\times2=-(3\times5\times2)=-30)

Step16: Substitute and calculate

For (-12d) with (d = 4), (-12d=-12\times4=-48)

Step17: Substitute and calculate

For (-4b^{2}) with (b = 2), (-4b^{2}=-4\times2^{2}=-4\times4=-16)

Step18: Substitute and calculate

For (a^{2}) with (a=-5), (a^{2}=(-5)^{2}=25)

Step19: Substitute and calculate

For (-5cd) with (c=-3) and (d = 4), (-5cd=-5\times(-3)\times4=5\times3\times4 = 60)

Step20: Substitute and calculate

For (13ab) with (a=-5) and (b = 2), (13ab=13\times(-5)\times2=-(13\times5\times2)=-130)

Step21: Substitute and calculate

For (3c) with (c=-3), (3c=3\times(-3)=-9)
