GIVEN:- 1 to 15

TO FIND:- how many perfect squares in 1 to 15

SOLUTION:-

• In mathematics, a square number or perfect square is any integer that is the square of an integer; in simple words, it is the product of some integer with itself. For example, 4 is a square number, since it equals 2² and can be written as 2 × 2.

The First 5 perfect squares are

$1 \times 1 = 1 \\ 2 \times 2 = 4 \\ 3 \times 3 = 9 \\ 4 \times 4 = 16 \\ 5 \times 5 = 25$

According to the question we need to find the perfect square between 1 to 15 so we'll only include 1, 4, and 9

Hence, there are 3 perfect squares in 1 to 15 which are 1,4 and 9
