To answer this question, we can see that:
We can see from the graph above that if we raise the number 7 to 2, we obtain 49. Thus, the logarithm of 49 in base 7 is 2. In other words, if we raise the base of the logarithm to 2 we obtain the value of x (49). That is:
[tex]\log _749=2\Rightarrow7^2=49[/tex]
Hence, the value for x is equal to 49.
