Question

what is the square root of 756 cm with method​

Answer 1

Answer:

there are 2 methods

1.) Prime Factorization

2.) Division

I will tell 1st method

Step-by-step explanation:

756 ÷ 2 = 378

378 ÷ 2 = 189

189 ÷ 3 = 63

63 ÷ 3 = 21

21. ÷ 3 = 7

7 ÷ 7 = 1

756 = 2 × 2 × 3 × 3 × 3 × 7

since 7 and 3 are not in pair, it is not a square number.

if all numbers are in pair using this method, then it is a square number.

but since there are 3 left out numbers here, 756 is not a square number

hope this helped you out :)
