Question

tricks to find out square root​

Answer 1

Answer:

Step-by-step explanation:

FOR example take 144

step 1 :and write like this

10 * 10 =100

20 * 20=400

30 *30 =900

and so ..We need only upto this,,,,

STEP 2:Now check where is 144 is coming ..So it between 100 and 400 that is between 10*10 and 20*20

so we can know that square root is between 10 and 20

Step 3; Now check the once place..its 4 in 144...so chance for 4 as one place between 10 and 20 is 12 (12*12) so square root is 12...Every teacher know this...It is better to ask teacher to explain in words so u will be cleared
