Answer 4

Do you understand it?

Answer 5

Should we call for backup?

Answer 6

First you would solve the equation
\(6^y=x\)
take log on both sides
\(log 6^y = log x\)
use the properties of exponents to change it to
\(y~log 6 = log x\)
or
\(\large y=\frac{log(x)}{log6}\)
Since the given equation has x=12,
substitute x=12 in the above equation and solve for y.
Use the point (12,y) to select the graph required.
