A(x)=3^x If 8 came out, what was dropped in?

Question

`A(x)=3^x`
If 8 came out, what was dropped in?

Answer 1

`3^x=8\\ x=\log_38`

Answer 2

`A(x) = 3^x`

8 comes out so we know that

`3^x = 8`


`\implies \log{3^x} = \log{8}`


`x\log{3} = \log{8}`


`x = \frac{\log{8}}{\log{3}}`


`x \approx 1.8928`
