Question

2012.(2011-x)+25=5 mũ 5 :5 mũ 3

Answer 1

2012.(2011-x) + 25 = 5⁵:5³ = 25

2012.(2011-x) = 25 - 25 = 0

2011 - x = 0

x = 2011 - 0 = 2011

Answer 2

2012.(2011-x)+25=5⁵:5³

=>2012.(2011-x)+25=5^5-3

=>2012.(2011-x)+25=5²

=>2012.(2011-x)+25=25

=>2012.(2011-x)=25-25

=>2012.(2011-x)=0

=>2011-x=0:2012

=>2011-x=0

=>x=0+2011

=>x=2011
