The owner of an apple orchard has a field of new trees that are growing and producing more apples each year. he wants to determine the average growth rate, or percentage increase, of the amount of apples produced by these trees over time. the amount of growth varies each year, so he decides to find the geometric mean, or average. the formula g= a ⎯ ⎯ √ ⋅ b ⎯ ⎯ √ g=a⋅b is used to find the geometric mean of two numbers. step 1 of 2 : over two years, the growth rate was 130% 130% and 140% 140% respectively. find the average growth rate for these two years. leave your answer in simplified radical form.
