Question

methods to find square roots​

Answer 1

there are two methods to find square roots :

factorisation method and,

long division method

Answer 2

Pick a number that when squared, comes close to (but is less than) the number whose square root you’re finding: 3 × 3 = 9. This is a better choice than 4: 4 × 4 = 16

Divide the number you’re finding the square root of (12) by the number you squared (3) in step 1: 12 ÷ 3 = 4

Average the closest square root (3) and the answer of step 2 (4): 3 + 4 = 7. 7 ÷ 2 = 3.5

Square the average to see how close the number is to 12:

3.5 × 3.5 = 12.25—Close, but not close enough!
