EXERCISE 3A
(1) Find the square of:
(i) 59 = 59 × 59 =
(ii) 6.3 = 6.3 × 6.3 =
(iii) 15 × 15 = 225
(2) By splitting into prime factors, find the square root of:
(5) Find the square root of:
(6) Evaluate:
(7) Evaluate:
(10) (13)2 = 169 and (31)2 = 961
Similarly, two such number can be 12 and 21
∴ (12)2 = 144 and (21)2 = 441
And 102, 201
(102)2 = 102 × 102 = 10404
And (201)2 = 201 × 201 = 40401
(11) L.C.M of 3, 4, 5 and 6 = 60
Also, 60 = 2 × 2 × 5 × 3 in which 5 and 3 are not in pairs.
So, 60 should be multiplied by 5 × 3 to get a perfect square number.
∴ The required least square number = 60 × 5 × 3 = 900.
