Answer:
The value of given expression [tex]log_7343[/tex] is 3.
Step-by-step explanation:
Given: [tex]log_7343[/tex]
We have to find the value of given expression [tex]log_7343[/tex]
Consider the given expression [tex]log_7343[/tex]
Rewrite 343 in base- power form as [tex]343=7^3[/tex]
We have
[tex]=\log _7\left(7^3\right)[/tex]
Apply log rule, [tex]\log _a\left(x^b\right)=b\cdot \log _a\left(x\right)[/tex]
We have ,
[tex]\log _7\left(7^3\right)=3\log _7\left(7\right)[/tex]
Again Apply log rule [tex]\log _a\left(a\right)=1[/tex]
we have [tex]\log _7\left(7\right)=1[/tex]
Thus, [tex]3\log _7\left(7\right)=3[/tex]
Thus, the value of given expression [tex]log_7343[/tex] is 3.
By rewriting the given expression with natural logarithms, we will see that:
log₇(343) = 2.99
How to find logarithms that aren't the natural logarithm?
There is a really simple rule for logarithms of base different than e, that can be written as:
logₐ(x) = ln(x)/ln(a)
Then the given equation:
log₇(343) can be rewritten as:
log₇(343) = ln(343)/ln(7)
Now we have only natural logarithms, and we can evaluate that using a calculator:
ln(343)/ln(7) = 5.84/1.95 = 2.99
