Question

How do i do this? log(3)2c= -2

Answer 1

3^-2=2c

Answer 2

solve for c

Answer 3

how you get 3^-2=2c

Answer 4

well log is just the inverse function of an exponent
logb x = y
is

b^y=x

And plug in your numbers and variables

Answer 5

\[b=a^{x}\]
then
\[x=\log_{a}b \]
so the power becomes the subject of the equation
but we are going back hence
\[3^{-2}=2c\]

Answer 6

so how do i solve for c

Answer 7

\[c=1/18\]

Answer 8

how do i solve for c

Answer 9

divide by 2 both sides and evaluate

Answer 10

\[2c=1/3^{2}\]
\[2c=1/9\]
\[c=1/9\div2=1/18\]
