square root of 535.9225??? explain with shortcut
@ nisha , the shortcut which I explained to you earlier cannot be used here , it can be used only for the perfect squares.
Here 535 is b/w (23)^2 = 529 & (24)^2 =576.
535 just above 529. , so it will be 23._ _.
Since there are 4 places after the decimal point in the number ,its square root will have two numbers after the ( . ) .
No ends with 25 ,so last digit will surely be 5 .
ie, 23._5 .
Since the no: is very much near the (23)^2 = 529 .
Ans will either be 23.05 or 23.15 .
