Question

The area covered by certain invasive plants triples each year. When the plants were first discovered in a
region, they covered 1 m
2
. Let y be the number of years since the plants were discovered in that region.
The plants now cover 243 m
2
. Which equation could be used to find how many years ago the plants
were first discovered?

Answer 1

It took 5 years for the plants to cover an area  of 243 m^2.

 

3^x = 243

 

3^x = 3^5

 

x = 5 years that's the equation we were looking for
