Question

Medal to whoever can answer
Evaluate log7 343.
49
3
−3
−49

Answer 1

\( \log_7 343\)
means what power do you raise 7 to, to get 343.

Answer 2

This is how you change form logarithmic notation to exponential notation.

\( \large \log_b x = y \iff b^y =x\)

Answer 3

In your case,

\( \large \log_7 343= y \iff 7^y = 343\)

You are looking for the exponent that you need to raise 7 to, to get 343.
