5871⁰ : [928 - (247 - 82).5] + 2175⁰
= 1 : (928 - 165.5) + 1
= 1 : (928 - 825) + 1
= 1 : (-103) + 1
= 102/103
\(5871:\left[928-\left(247-82.5\right)\right]\\ =5871:\left[928-\left(247-410\right)\right]\\ =5871:\left[928-\left(-163\right)\right]\\ =5871:1091\\ =\dfrac{5871}{1091}\)
\(=\dfrac{5871}{928-\left(247-410\right)}=\dfrac{5871}{928-247+410}\)
\(=\dfrac{5871}{1091}\)
\(5871:\left[928-\left(247-82\cdot5\right)\right]\)
\(=5871:\left[928-\left(247-410\right)\right]\)
\(=5871:\left(928+163\right)\)
\(=5871:1091\)
\(=\dfrac{5871}{1091}\)
b) m nhân với tổng của n và p, với m = 9 ; n = 1069 ; p = 2175
N + P = 1069 + 2175 = 3244
M x ( N + P) = 9 x 3244 = 29196
HT
= m x n +p = 9 x (1069 + 2175 )
= 9 x 3244
= 29196

a) \(9\cdot2^3-72:2^2\)
\(=72-18=54\)
b) \(125\cdot26+5^3\cdot32+25\cdot42\cdot5\)
\(=125\cdot26+125\cdot32+125\cdot42\)
\(=125\cdot\left(26+32+42\right)=125\cdot100=12500\)
c) \(5871:\left[928-\left(247-82\right)\cdot5\right]+2012^0\)
\(=5871:\left[928-\left(247-82\right)\cdot5\right]+1\)
\(=5871:\left(928-165\cdot5\right)+1\)
\(=5871:103+1\)
\(=58\)
d) \(2012+78+\left(-178\right)+\left(-2012\right)\)
\(=\left[2012+\left(-2012\right)\right]+\left[78+\left(-178\right)\right]\)
\(=-100\)
a, \(9.2^3-\frac{72}{2^2}=9.8-\frac{72}{4}=72-18=54\)
b, \(125.26+5^3.32+25.42.5\)
\(=125.26+125.32+125.42\)
\(=125.\left(26+32+42\right)\)
\(=125.100\)
\(=12500\)
c, \(\frac{5871}{\left[928-\left(247-82\right).5\right]}+2012^0\)
\(=\frac{5871}{103}+1\)
\(=57+1\)
\(=58\)
d, \(2012+78+\left(-178\right)+\left(-2012\right)\)
\(=\left[2012+\left(-2012\right)\right]+\left[78+\left(-178\right)\right]\)
\(=0+100\)
\(=100\)
