equivalent to what is a expression equivalent to log18 – log(p + 2)?
familiar with the log properties ?
nall but they gave me choices log p+2/18 , log 18/p+2 , log20/p log{18 times (p+2)]
nope log property that suppose to be on ur notes :-)
anyways quotient rule\[\large\rm log_b y - \log_b x = \log_b \frac{ x }{ y}\]to condense you can change subtraction to division product rule \[\large\rm log_b x + \log_b y = \log_b( x \times y )\] addition ----> multiplication power rule \[\large\rm log_b x^y = y \log_b x\] hint: \[\large\rm log_b x = \log_b y\] \[\large\rm\cancel { log_b} x = \cancel{\log_b} y\] x=y
so which one you should apply ?
the second one
so my answer is D
\[\huge\rm log18 \color{ReD}{–} \log(p + 2)\] there is a negative sign so which property you should apply here ?
the quotient rule
yes that's right so \[\huge\rm log18 \color{ReD}{–} \log(p + 2)= ???\]
log{18 times (p+2)]
quotient \[\large\rm log_b x- \log_b y = \log_b \frac{ x }{ y}\] same like this property log x/y
quotient rule when there is a negative sign change that to DIVISION
oh so its log 18/p+2 ,
yes right
i got lot more questions help me
