Answer 1

0,666... = 6/9 = 2/3

$8^{\frac{2}{3} } + 4^{\frac{3}{2} } - 2^{\sqrt{9}} + 9^{0,5}$

$\sqrt[3]{8^{2} } + \sqrt{4^{3} } - 2^{3} + \sqrt{9}$

$\sqrt[3]{64} + \sqrt{64 } - 8 + 3$

$4 + 8 - 8 + 3$

$7$

$\frac{1}{49} ^{\frac{1}{2} }$

$\sqrt{\frac{1}{49} }$

$\frac{\sqrt{1} }{\sqrt{49} }$

$\frac{1}{7}$

____________________

7 /  1/7

= 7 . 7/1

= 49

Resposta: 49
