Calculation skills trick

Calculation:

Step(1):

First, we will take the digit at the unit’s place.

At the unit place, we have 3.

Step(2):

Now consider the cube table, the cube of which number has 3 as at the unit digit place.

We see, 7 x 7 x 7 = 343.

Step(3):

That means the cube root of 50653 will have 7 at the unit place.

Step(4):

Now ignore the last 3 digits of 50653, i.e. 653

Step(5):

Taking 50 as a reference number, we can see from the cubes table 50 lies between cubes of 3 and 4.

Step(6): Here, we choose the lower number i.e. 3

∴ We get the two digit of the answer

∴ Cube root of 50653 = 37
