Question

What is the value of log Subscript 7 Baseline 343?

Answer 1

the answer is 3

Explanation:

Answer 2

`log_7(343)=3`

Explanation:

The value of
`log_7(343)` can be easily obtained by recalling what the log notation means. Recall that logarithms are another way of writing exponents.

With the notation
`log_7(343)=?` we want to find an exponent (logarithms are exponents). So read this expression as: what is the exponent we need to use on base "7" to get the number 343? That exponent is the answer to the question.

Equivalently in exponential form: What is the exponent "x" such that:
`7^x=343`. The answer to this is : "3" (the exponent 3 on base "7" renders 343)

"3" is the answer because
`7^3=343`
