CORRECT ANSWER : 42
EXPLANATION :
√1764
We should split that square root sum into two half(first two digit last two digit) first we consider last two digit
See the last digit in this sum 4 is the last digit now we should remember the square table which are the numbers end in 4 digit in square tables they are two numbers end in 4 digit i) 2×2=4 ii) 8×8=64
We should choose 1 in these two number(2 or 8) How to choose them correctly I will tell it few steps
Now take first two digit in this sum the digit 17 which square number is close to 17 ( we all know 16 , 4×4 =16 you will get 4 and then add 5 why we add 5 because what will be number get in the first digit answer add next digit in this sum we getting answer is 4
next digit 5 we should multiply 4×5=20
Now you should compare 20 and 17(first two digit number)
20>17 you should choose 2(last two digit number) so the answer we got it is:
