Answer 2

Answer:

30³ + 20³ - 50³ = -90000

Step-by-step explanation:

evaluate (30)3+(20)3-(50)3

Different method to evaluate

30³ + 20³ - 50³

= 27000 + 8000 - 125000

= 35000 - 125000

= -90000

30³ + 20³ - 50³

= (3*10)³ + (2*10)³ - (5*10)³

= 27*10³ + 8*10³ - 125*10³

= 10³(27 + 8 - 125)

= 1000(-90)

= -90000

30³ + 20³ - 50³

a³ + b³ = (a +b)³ - 3ab(a+b)

a = 30

b = 20

= (30 + 20)³ - 3(30)(20)(30 + 20) - 50³

= 50³ - 1800(50) - 50³

= -90000
