Q4 q12.) solve the following logarithmic equation. be sure to reject any value of x that is not in the domain of the original logarithmic expression. give the exact answer.  

Hi again!



Ok so we need to solve that by converting the logarithm to exponential form. We know that the expression is equal to x = a^b

Thus,

x + 7 = 7²

x + 7 = 7 * 7

x + 7 = 49

Then subtract 7 on both sides

x + 7 - 7 = 49 - 7

x = 42

Let me know if you have any questions.

P.S. I am learning these this year, so I am not really good at explaining them. But of course my answers are correct :)

Sorry i don't really know and i don't have time
