Question

without actually calculating the cubes , find the value of. (0.2)^3-(0.3)^+(0.1)^3​

Answer 1

Answer:

0.018

Step-by-step explanation:

Let 0.2 =a

- 0.3 =b

0.1=c

Here a+b+c =0

Therefore, a cube + b cube + c cube = 3(a into b into c)

Therefore 0.2 cube + (-0.3) cube + 0.1 cube =3(0.2 into - 0.3 into 0.1)=-0.018
