Calculation skills trick
Calculation:
Step(1):
First, we will take the digit at the unit’s place.
At the unit place, we have 4.
Step(2):
Now consider the cube table, the cube of which number has 4 as at the unit digit place.
We see, 4 x 4 x 4 = 64.
Step(3):
That means the cube root of 13824 will have 4 at the unit place.
Step(4):
Now ignore the last 3 digits of 13824, i.e. 824
Step(5):
Taking 59 as a reference number, we can see from the cubes table 13 lies between cubes of 2 and 3.
Step(6): Here, we choose the lower number i.e. 2
∴ We get the two digit of the answer
∴ Cube root of 13824 = 24
