Question

Calcule el valor de "A+B":

Answer 1

Respuesta:

17/9=1,888...

Explicación paso a paso:

$A=\sqrt[4]{\frac{16}{81} } -\sqrt[3]{\frac{27}{8} } \\A=\frac{2}{3}-\frac{3}{2} \\A=\frac{4-9}{6} \\\\A=\frac{-5}{6} \\\\B=\frac{4}{9}-\sqrt{2\frac{1}{4} } \\B=\frac{4}{9}-\sqrt{\frac{9}{4} }\\B=\frac{4}{9}-\frac{3}{2} \\B=\frac{8-27}{18} \\B=\frac{-19}{18}$

HALLAMOS A+B

$\frac{-5}{6}+(-\frac{19}{18} )\\\frac{-5}{6}-\frac{19}{18}\\\frac{-15-19}{18} \\\frac{-34}{18} \\\frac{17}{9} =1,8888...$
