Question

solve for x , 2x^2x = 9^x-3

Answer 1

can you clarify exponents with parenthesis?

Answer 2

2x^(2x) = 9^(x-3)

Answer 3

hmm since you have a x^x term , im not sure if this solvable using algebra

Answer 4

take log both sides
\[2x \ln x = (x-3) \ln 9 - \ln 2\]
\[x(2\ln x - \ln9) = -3\ln 9 -\ln2 \]

...no way to isolate "x" since it both inside log and outside

Answer 5

ok thank you
