100=25 .4 =5^2.4
5^2019:( 5^2013-5^2.4.5^2010)=5^2019: ( 5^2013-5^2012.4)=5^2019: (5^2012.(5-4))
=5^2019:5^2012=5^7(=78125)
Học tốt
5x = 52019 : (52013 -100*52010)
<=> 5x = 52019 : (52010 .(53-100))
<=> 5x = 52019 : (52010 . 25)
<=> 5x = 52019 : 52012
<=> 5x = 57
<=> x = 7
Vậy x = 7
5x=52019:(52013-25*4*52010)
5x=52019:(52012*5-52012*4)
5x=52019:52012
5x=57
Vậy x=7
Ta có:
5x = 52019 : (52013 - 100*52010)
5x = 52019 : [52010 (53 - 100)]
5x = 52019 : [52010 (125 - 100)]
5x = 52019 : (52010 * 25)
5x = 52019 : (52010 * 52)
5x = 52019 : 52012
5x = 57
\(\Rightarrow\)x = 7
ak bài mk thì kết luận x=7 nhé sory hơi vội kkk
