Question

Tìm x biết (6+5x)^50=36^25

Answer 1

\(\left(6+5x\right)^{50}=36^{25}\)

\(\left(6+5x\right)^{50}=6^{50}\)

\(\Rightarrow6+5x=6\)

\(\Rightarrow5x=0\)

\(\Rightarrow x=0\)

vay \(x=0\)

Answer 2

(6+5x)⁵⁰=36²⁵

=> [(6+5x)² ]²⁵=36²⁵

=> (6+5x)²=36

=> (6+5x)²=6²

=> 6+5x=6

=> 5x=0

=> x=0

Answer 3

\(\left(6+5x\right)^{50}=36^{25}\)

\(\left(6+5x\right)^{50}=\left(6^2\right)^{25}\)

\(\left(6+5x\right)^{50}=6^{50}\)

=> \(6+5x=6\)

      \(5x=0\)

       \(x=0\)
