5,1,and 25 i think
The square root of 25 is 5, which is a whole number, an integer, a natural number and a rational number.
Yes
It's both.
The first 3 digit natural number is 100: 100 ÷ 4 = 25 → first 3 digit natural number divisible by 4 is 4 × 25 The last 3 digit natural number is 999: 999 ÷ 4 = 249 r 3 → last 3 digit natural number divisible by 4 is 4 × 249 → number of 3 digit natural numbers divisible by 4 is 249 - 25 + 1 = 225.
All of them except irrational number.
The positive square root is.
25
(1 + 25) x 25/2 ie 425. The sum of the first n integers is (n + 1) x n/2
1, 2, 4, 5, 10, 20, 25, 50, 100
