12x - 10x = 5^8 : 5^4 + 201^0
2x = 5^4 + 1
2x = 625 + 1
2x = 626
x = 626 : 2
x = 313
\(12x-10x=5^8:5^4+201^0\)
\(\Rightarrow x\left(12-10\right)=5^4+1\)
\(\Rightarrow2x=625+1=626\)
\(\Rightarrow x=626:2=313\)
Vậy x = 313
12x - 10x = 5^8 : 5^4 + 201^0
2x = 5^4 + 1
2x = 625 + 1
2x = 626
x = 626 : 2
x = 313
\(12x-10x=5^8:5^4+201^0\)
\(\Rightarrow x\left(12-10\right)=5^4+1\)
\(\Rightarrow2x=625+1=626\)
\(\Rightarrow x=626:2=313\)
Vậy x = 313
