Correct option is BGiven: √4 = ? Concept Used: the radical symbol √ is defined to give the principal (non-negative) square root. By convention, The equation x2 = 4 has two solutions, x = ±2\pm 2±2 Solution: Factor the number: 4 = 2×\times×2 So, 4=2×2\sqrt4 =\sqrt{2\times 2}4=2×2 = 222 As a result, the value of 4 is 2
