Giải nhah nha các bn

Answer 1

33^x :11x =81
↔\(\frac{33^x}{11^x}\)=81
↔(\(\frac{33}{11}\))^x=81

↔3^x=81
→x=4

Answer 2

\(33^x:11^x=81\)

\(=>\left(33:11\right)^x=81\)

\(3^x=81\)

\(3^x=3^4\)

\(=>x=4\)

Vậy x = 4

Answer 3

\(33^x:11^x=81\)

\(\Rightarrow\left(33:11\right)^x=81\)

\(\Rightarrow3^x=81\)

\(\Rightarrow x=4\)

Vậy : \(x=4\)

Answer 4

33^x : 11^x=81
