\(5871:\left[928-\left(247-82.5\right)\right]\\ =5871:\left[928-\left(247-410\right)\right]\\ =5871:\left[928-\left(-163\right)\right]\\ =5871:1091\\ =\dfrac{5871}{1091}\)
\(=\dfrac{5871}{928-\left(247-410\right)}=\dfrac{5871}{928-247+410}\)
\(=\dfrac{5871}{1091}\)
\(5871:\left[928-\left(247-82\cdot5\right)\right]\)
\(=5871:\left[928-\left(247-410\right)\right]\)
\(=5871:\left(928+163\right)\)
\(=5871:1091\)
\(=\dfrac{5871}{1091}\)
a, \(\left[2^3.\left(2+3\right)^3-3^2.111-1000^0\right]:15^0+1^3\)
\(=\left[8.5^3-9.111-1\right]:1+1\)
\(=\left[1000-999-1\right]:1+1=1\)
b, \(5871:\left\{928-\left[\left(-82\right)+247\right].5\right\}\)
\(=5871:\left[928-165.5\right]=5871:\left(928-825\right)\)
\(=5871:103=57\)
c, \(2^7:2^3+2^3.2^0+3^2.3^0.2-1^{20}\)
\(=2^4+2^3+9.2-1\)
\(=16+8+18-1=41\)
d, \(36.27+36.73-249\)
\(=36.\left(27+73\right)-249=36.100-249\)
\(=3600-249=3351\)
Chúc bạn học tốt!!!

5871⁰ : [928 - (247 - 82).5] + 2175⁰
= 1 : (928 - 165.5) + 1
= 1 : (928 - 825) + 1
= 1 : (-103) + 1
= 102/103
