8 0

Answer:

  \log_{19}{361}=2

Step-by-step explanation:

We know that taking logarithms performs the transformation ...

  b^e=x\\\\e\cdot\log{b}=\log{x}\quad\text{take logs}\\\\e=\dfrac{\log{x}}{\log{b}}\quad\text{divide by $\log{b}$}\\\\\log_b{x}=e\quad\text{use the change of base formula}

Then for b=19, e=2, x=361, we have

  \boxed{\log_{19}{361}=2}
