Formula For this tricks:

Let ‘pq’ be a two number that we want to find the square.

〈pq〉²=?

Ans:

  • Split the number into two parts

p↔q

  • Now find the square of each digit

let (p)²=p²

& (q)²=q² (If the square of q is an one digit number then Write it as 0q²)

  • Now find 20×p×q = 20pq (We have to multiply each digit p & q by 20, here 20 is fixed)

  • So the square of the number (pq) will be p²0q²+20pq=z
