Question

What is 3^9x when 27^x=4

And solve for (2^x)3x+3x=1

(two different questions^)

Answer 1

\[27^x=4\] so
\[3^{3x}=4\]

Answer 2

but the bases are not the same :(

Answer 3

they are now

Answer 4

\[27=3^3\]so
\[27^x=3^{3x}\]

Answer 5

No, i mean 3 is not the same with 4

Answer 6

since
\[3^{3x}=4\] you can compute
\[3^{9x}=(3^{3x})^3\]

Answer 7

Yeah, but what about 4?

Answer 8

the 4 is what you are going to cube

Answer 9

\[3^{9x}=(3^{3x})^3=4^3\]
