Question

6x+x=5^11:5^9+3^1

Answer 1

Ta có: \(6x+x=5^{11}:5^9+3^1\\ < =>7x=5^2+3^1\\ < =>7x=25+3=28\\ =>x=\dfrac{28}{7}=4\)

Answer 2

Có:

\(6x+x=\dfrac{5^{11}}{5^9}+3^1\)

\(\Rightarrow7x=5^2+3=25+3=28\)

\(\Rightarrow x=\dfrac{28}{7}=4\)

Vậy \(x=4\).

Học tốt!

Answer 3

\(6x+x=5^{11}:5^9+3^1\)

\(\Leftrightarrow7x=5^{11-9}+3\)

\(\Leftrightarrow7x=5^2+3=25+3=28\)

\(\Leftrightarrow x=28:7=4\)

Vậy \(x=4\)

Chúc bạn học tốt!!!

Answer 4

6x + x = 5¹¹:5⁹ + 3¹

=> 7x = 5² + 3¹

=> 7x = 28

=> x = 28 : 7

=> x = 4
