Question

Logarithmic fuctions

Answer 1

\[\log_{7} 7^9\]

Answer 2

Need help on how to do this thank you!

Answer 3

\[\log_{7} 7^9\]

Answer 4

well, log x = y is the number that when we elevate the base with exponent y it gives x, then 7(base)^y(log)=7^9 -> then y = log = 9

Answer 5

I don't think that is clear, sorry english is not my native language.

Answer 6

YEs it would be easier if you used the equation images

Answer 7

Thank you

Answer 8

The problem is that I used the definition of log so I don't think it would help to use the equation images, but lets try.
\[\log_{a} x=y \]By the definition:\[a^y=x\]So when you have x = a^b, by the second equation y = b.
Better?

Answer 9

Yes much better thank you
