Question

Determine o valor de x=[-(4/3)^-1 - 1, 25]^-5

Answer 1

$x= [- ( \frac{3}{4} )^{1} - \frac{125}{100} ]^{-5} \\ \\ x= [-\frac{3}{4} - \frac{125}{100} ]^{-5} \\ \\ x= [ \frac{25*(-3)-125}{100} ]^{-5} \\ \\ x= [\frac{-75-125}{100}] ^{-5} \\ \\ x= [ \frac{-200}{100}] ^{-5} \\ \\ x=-2^{-5} \\ \\ x= [ \frac{1}{-2} ]^{5} \\ \\ x= \frac{1}{-32}$
