Question

Find the cube root of -2.744  [4 MARKS]


Solution

Concept: 1 Mark
Application: 2 Marks

2.744=27441000

By estimation 2744 = 2(group 1)  744(group 2)

The second group has 4 as its unit digit. Therefore, its root will also have 4 at its unit digit.

Now 2 lies between 1 and 8 which is the cube of 1 and 2 respectively.

1 being the smaller of these, the tens place of the cube root will be 1.

So the cube root will be 14

Cube root of 1000 = 10

(27441000)13=1410=1.4
