Convert the following equations into logarithmic form:
a. 9 = 4x
b. 3 = 6y
c. 5 = 7y
d. X = 9y
I have tried but am unsure still. Please help.
Hello, LisaAnn_86!
I assume that these are exponential statements.
You're expected to know the conversion:Convert the following equations into logarithmic form:
$\displaystyle a)\;\; 9 \:= \:4^x$
. . $\displaystyle N \:=\:b^x\quad\Longleftrightarrow\quad \log_b(N) \:=\:x$
Therefore: .$\displaystyle 9 \:=\:4^x\quad\Rightarrow\quad \log_4(9) \:=\:x$
$\displaystyle 3 \:=\:6^y\quad\Rightarrow\quad \log_6(3) \:=\:y$$\displaystyle b)\;\;3 \:= \:6^y$
. . . . . Get it?
