Answer 6

log property

\[\log_{b}a^b =b*\log_{b}a \]

Answer 7

My confusion is when graphing or finding the domain

Answer 8

ignore that i used b twice in the same side. a^c

Answer 9

when i graphed log8(x^2)
it gives me a domain from (-00,0) U (0,00)
while when using the power rule
it is just from (0,00)

Answer 10

I don't get how that can happen..

Answer 11

x can be negative or positive when it is squared

Answer 12

Yes but aren't the two function equivalent ?
and should therefore have the same domain

Answer 13

look at the first blue box rules there
