**Square of numbers ending in 5***75 × 75 or 75²*

We simply multiply 7 by the next number i.e. 8 to get 56 which forms the first part of the answer and the last part is simply 25 = (5)².

So, 75 × 75 = 5625

This method is applicable to numbers of any size.

Example:

*605²*
60 × 61 = 3660 and 5² = 25

∴ 605² = 366025
