Hello there,

In order to find the value of log
`_(7)`(343) you need to understand on how to write this logarithms as exponents:

• log
  `_(7)`(343) = x would be
  `x^(7)`= 343

Now simply plug the logarithm into a calculator and you should get 3 as your answer.

To check you solve
`3^(7)` and you should get 343.

Therefore your answer would have to be 3 for the logarithm.

Hope I helped,
