We can solve this problem by using the formula for exponential growth, which in this context is , where:

 is the final amount (the height of the tree after  years).

 is the initial amount (the starting height of the tree). Here, .

 is the growth rate as a decimal. Given that the growth rate is , we convert it to a decimal by dividing by , so .

 is the number of years. In this case,  years.

Now we substitute these values into the formula:
