Solve for x:
(9 log(x))/(log(10)) = 2

Divide both sides by 9/(log(10)):
log(x) = (2 log(10))/9

(2 log(10))/9 = log(10^(2/9)):
log(x) = log(10^(2/9))

Cancel logarithms by taking exp of both sides:
Answer: |x = 10^(2/9)=1.6681

log 10 (base 10) is 1 ??

\(9 log x = 2\\ logx=2/9\\ x=10^{(2/9)}\\ x=100^{1/9}\\ x=\sqrt[9]{100} \)
