Question

-[(1/7)²-√√1/81]-{√√³√e²⁴+1}​

Answer 1

Respuesta:

a) 3.0204

b) -41.9

Explicación paso a paso:

$a) -[(\frac{1}{7})^{2} -\sqrt{\sqrt{\frac{1}{81} } }]-[\sqrt{\sqrt{\sqrt[3]{e^{24} } } } +1]$

$-[\frac{1}{49}-\sqrt[4]{81} ]-[\sqrt[12]{e^{24} } +1]$

$-[\frac{1}{49}-\frac{3*49}{49} ]-[e^{2}+1 ]$

$-[\frac{1-147}{49}] -[2.7182^{2}+1 ]$

$-[-\frac{148}{49}] -[7.38861124+1]$

$\frac{148}{49}-8.38861124$

$3.0204$

$b) (\sqrt{\frac{1}{6} } \sqrt{-\frac{1}{6} } )^{-2} -(\frac{\sqrt{72} }{\sqrt{2} } -\sqrt{(0.33333....)^{4} } )$

$(\sqrt{-\frac{1}{36} } )^{-2} -(\frac{\sqrt{72} }{\sqrt{2}}-(\frac{3}{9} )^{2} )$

$\frac{1}{-\frac{1}{36} } -(\frac{\sqrt{72} }{\sqrt{2} }*\frac{\sqrt{2}}{\sqrt{2}} -\frac{9}{81} )$

$-36-(\frac{\sqrt{144} }{2}-\frac{9}{81} )$

$-36-(\frac{12}{2}-\frac{9}{81} )$

$-36-(\frac{81*12-9*2}{81*2} )$

$-36-(\frac{954}{162} )$

$-36-5.9$

$-41.9$
