Question

How many natural n numbers are there II in square off of 36 and 35

Answer 1

36^2 = 1296

35^2 = 1225

Number of natural numbers between 1296 & 1225 = 1296 - 1225 - 1 = 70 ——> Answer

Note: -1 is added to the above to ignore 1296 as they asked for numbers between 1296 & 1225. If we don’t put -1 it will include 1296 as well.

Ex: Number of natural numbers between 5 & 10 are 6, 7, 8 & 9 which are totally 4 numbers only. That means 10 - 5 - 1 = 4
