Question

3 mũ x+4 = 27 mũ 10

Answer 1

\(3^{x+4}=27^{10}\)

\(3^{x+4}=\left(3^3\right)^{10}\)

\(3^{x+4}=3^{30}\)

\(\Rightarrow x+4=30\)

\(\Rightarrow x=26\)

Vậy x = 26

Answer 2

\(3^{x+4}=27^{10}\)

\(\Rightarrow3^{x+4}=\left(3^3\right)^{10}\)

\(\Rightarrow3^{x+4}=3^{30}\)

\(\Rightarrow x+4=30\)

\(\Rightarrow x=30-4=26\)

Vậy x = 26

Answer 3

\(3^{x+4}=27^{10}\)

\(3^{x+4}=\left(3^3\right)^{10}\)

\(3^{x+4}=3^{30}\)

\(\Rightarrow x+4=30\)

           x= 30-4

           x= 26

Vậy x= 26
