How to calculate Square root? in an easy way.........


Sagot :

think what number you can multiply by theirselves that the answer is the number
 
you use T.A.E or Trial And Error
By using factors but use same number if possible but if can't then you can use other numbers.
Ex.:
√4 = 2x2 or 2² = put one of the 2 outside because it has a square(²) and = 2√1 or 2
√20 = 2x2x5 or 2²x5 = put one of the 2 outside = five will be left inside because it doesn't have ² = 2√5 or 4.47
