Question

Can someone explain logarithm to me?

Answer 1

properties ??

Answer 2

well the key concept in my textbook is confusing. it says that A logarithm base b of a positive number x satisfies the following definition:
\[For~b>0,~ b \neq0,~\log_bx=y~if~and~only~if~b^y=x.\]

Answer 3

can you explain that to me?

Answer 4

quotient rule\[\huge\rm log_b y - \log_b x = \log_b \frac{ x }{ y}\]
to condense you can change subtraction to division
product rule \[\huge\rm log_b x + \log_b y = \log_b( x \times y )\]
addition ----> multiplication

power rule \[\huge\rm log_b x^y = y \log_b x\]

Answer 5

that's Greek to me. I haven't even gotten past the key concept yet XD

Answer 6

okay exponential to log form \[\huge\rm \log_b x = y \]

base >0
common log base to 10
wait...
