Answer:
Option 3: take base-4 log each side
In case of multiple answers:
Options 3,4 & 5
Step-by-step explanation:
4^(x+3) = 18
Apply log4 both sides to being the power down
You can take log with any other base too.
In case of multiple answers, options 4 and 5 are also valid
Take the log of each side, any base will work
so log4, loge or log10
4^ (x+3) = 18
Take the log of each side
loga (4^ (x+3)) = loga 18
We can the take the exponents outside of the log
(x+3) loga 4 = loga 18
Divide each side by loga 4
(x+3) = loga 18 /loga 4
Subtract 3 from each side
x = loga 18 /loga 4 -3
the answer will be 9 dollars
the answer is c
(2x +3) (4x +y)
