Question

urgentissímo, podem me ajudar?​

Answer 1

g)

${2}^{ - 3} + {2}^{ - 1} + \sqrt{25} + {( - 7)}^{0}$

$\frac{1}{8} + \frac{1}{2} + 5 + 1 = \frac{1 + 4 + 40 + 8}{8} = \frac{53}{8}$

h)

$\frac{ \sqrt{1 + \sqrt{289} } }{ \sqrt{21 + \sqrt{121} } } = \frac{ \sqrt{1 + 17} }{ \sqrt{21 + 11} } = \frac{ \sqrt{18} }{ \sqrt{32} }$

$\sqrt{ \frac{18}{32} } = \sqrt{ \frac{9}{16} } = \frac{3}{4}$
