The given number = 84

Concept:

Calculation skills trick

Calculation:

Step - 1

Write down the squares of each of the digits in two digit format i.e. 8² = 64 and 4² = 16

The number obtained after this step is 6416.

Step – 2

Multiply the digits with each other and also with the power 2 i.e. 8 × 4 × 2 = 64

Step – 3

Add the number obtained in step - 2 with the number obtained in step – 3 keeping the unit place empty i.e.

6 4 1 6
