1.	If x is a positive real number and x2 = 2, then x3 =A. \(\sqrt2\)B. \(2\sqrt{2}\)C. \(3\sqrt{2}\)D. 4
Answer» x² = 2 x = \(\sqrt2\) x ³ = (2)^1/2 ^{× 3} = 2\(\sqrt2\)

If x is a positive real number and x2 = 2, then x3 =A. \(\sqrt2\)B. \(2\sqrt{2}\)C. \(3\sqrt{2}\)D. 4

Answer»

x² = 2

x = \(\sqrt2\)

x ³ = (2)^1/2 ^{× 3}

= 2\(\sqrt2\)
