Question

1 cube + 2 cube+................ + 9 cube= 2025
then the value of (0.11)cube + (0.22 ) cube+.................. (0.99) cube is closed to

Answer 1

GIVEN:-

1³ + 2³ + 3³ + .........9³ = 2025.

Now,

We have to find (0.11)³ + (0.22)³ + (0.33)³ +........(0.99)³

so, we can write this "(0.11)³ + (0.22)³ + (0.33)³ +........(0.99)³"
as like this,

(1*11/100)³ + (2*11/100)³ + (3*11/100)³+.........(9*11/100)³

now take common' (11/100)³ '

We get,

(11/100)³ [ 1³ + 2³ + 3³ + ..........9³ ]

= (11/100)³ * (2025)
(As given above)

= (1331*2025)/(100³)

= (2695275)/(1000000)

= 2.695275

Answer 2

Answer:

2.695275
