Basic rules:**

There are some basic rules which are very useful for mental calculation. The rules are given below-

— If the square root contains n digits then the number must consist of 2n or 2n-1 digits

— But in case of pure decimals no of digits in the square is always double

— An exact square can’t end in 2 ,3,7 or 8

— A complete square ending in 1 must have either 1 or 9 as the last digit

— The square can end in 4 if the square root end in 2 or 8

—
i.e. the squares
of complements (from 10) have the same last digit. Thus 3^{2}&7^{2},
4^{2}&6^{2}

have the same last digit .
