SQUARE ROOTS TRICKS FOR FAST CALCULATION
square is the important chapter in maths. 2-3 question are always based on this topics in every exams. While in banking 8 – 10 question are based on this square chapter or on the bases of square
we provide tricks how to calculate SQUARE fast within seconds
if you practice, practice and practice I think you will be able to solve square to 30 to 130 within few seconds and you can save time is exams.
In this article we are solving squares
number with last digit 5.
from 30 to 50.
from 50 to 80.
from 80 to 100.
from 100 to 130.
from 30 to 50.
from 80 to 100.
from 100 to 130.
# Division Method
Step 1. Make Pair of digits of given number from left to right
Step 2. Pick first pair, like here 6 find the square which is equals to 6 or less than it.Like 2
Step 3. So Place it to in the section of Quotient as well as in the divisor.
Step 4: then subtract from square of no which is equals to 6 or less than it with 6
Step 5. Now comes to second pair bring it down like here 40 ,double the quotient like 2 = 4 and write the result on the left of 240 .It is just like division.Now repeat From Step 2 until you got the remainder zero.
# Prime Factor Method
# Square Root of a Decimal Fraction
Step 1. Make the pair of integer part first.
Step 2. Now find whether the decimal part is odd or even if it is odd then make it odd by placing at the end of it zero.
Now just find the square root by the division method as discussed above and don't forget to put the decimal point in the square root as the integer part is over.
