Explicação passo-a-passo:
[tex] \frac{1}{2} \times {36}^{ \frac{1}{2} } + 2 \times {36}^{ - \frac{1}{2} } = \\ \\ \frac{1}{2} \times \sqrt{36} + 2 \times { \sqrt{36} }^{ - 1} = \\ \\ \frac{1}{2} \times 6 + 2 \times {6}^{ - 1} = \\ \\ \frac{6}{2} + 2 \times \frac{1}{6} = \\ \\ 3 + \frac{2}{6} = \\ \\ 3 + \frac{1}{3} = \\ \\ \frac{(3 \times 3) + 1}{3} = \\ \\ \frac{9 + 1}{3} = \\ \\ \frac{10}{3} [/tex]
