Answer 1

Qual o valor de x na expressão abaixo?

$\mathsf{x=\dfrac{3^{-2}+2^{-1}}{\sqrt{1+5.4^{-1}}}+5\dfrac{\sqrt{\frac{16}{9}}}{6}}$

$\mathsf{x=\dfrac{\frac{1}{9}+\frac{1}{2}}{\sqrt{1+\frac{5}{4}}}+5.\dfrac{\frac{4}{3}}{6}}$

$\mathsf{x=\dfrac{\frac{11}{18}}{\sqrt{\frac{9}{4}}} + 5. \dfrac{2}{9} }$

$\mathsf{x=\dfrac{\frac{11}{18}}{\frac{3}{2}}+\dfrac{10}{9}}$

$\mathsf{x=\dfrac{11}{27}+\dfrac{10}{9}=\dfrac{11+30}{27}}\\\large\boxed{\boxed{\boxed{\boxed{\mathsf{x=\dfrac{41}{27}}}}}}$

a) 1/27

b) 41/27✅

c) 1/17

d) 11/18
