Question

write the square number in between 1to20​

Answer 1

Step-by-step explanation:

$\sqrt{1} = 1 \\ \sqrt{4} = 2 \\ \sqrt{9} = 3 \\ \sqrt{16} = 4$

therefore square no. between 1 to 20 are 4, 9, 16.

moreover 1 will not be included because we have found square no. "between" 1 to 20 in which 1 and 20 are not included.

11² = 121

12² = 144

13² = 169

14² = 196

15² = 225

16² = 256

17² = 289

18² = 324
