Question

2. Find the square roots of the following numbers by using their ones and tens digits.
(a) 1764
(6) 1444
(c) 3025
(d) 4761​

Answer 1

Step-by-step explanation:

a) the ones digit of this no. =4

ones digit of square root =2 or 8

let us strike out two digits from the right then the number = 17

4×4 < 17 < 5×5

hence tens digit of square root =4

so, 1764=48 or 42

but square of 48 that is 2304, which is not equal to 1764 hence 1764= 42
