A) a natural number |
B) a integer and not a natural number |
C) a rational number but not an integer |
D) a real number but not a rational number |
D) a real number but not a rational number |
Given expression = \( \Large \left[ \left(\sqrt{2}\right)^{\sqrt{2}} \right]^{\sqrt{2}} \)
= \( \Large \left(\sqrt{2}\right)^{ \left(2\right)^{\frac{\sqrt{2}}{2}} } = \left(\sqrt{2}\right)^{ \left(2\right)^{\frac{1}{\sqrt{2}}} } \)
= \( \Large \left(2\right)^{\frac{1}{2} \times 2^{\frac{1}{\sqrt{2}}}} = 2^{ \left(\frac{2}{2}^{\frac{1}{\sqrt{2}}}\right) } = \left(2\right)^{ \left(2\right)^{ \left(\frac{1}{\sqrt{2}}-1\right) } } \)
which denotes a real number but not a rational number.
