Without using a calculator. find the exact value of log, 81 - log,. 1 log2 0- 8 log 0.001

Without using a calculator. find the exact value of log,[log 3(1og, 8)].

Without using a ca lculator, determine which is the greater number: log, 60 or log, 40.

This group exercise involves exploring the way we grow. Group members should create a graph for the function that models the percentage of adult height allained by a boy who is x years old, f(x) - 29 + 48.8 1og(x + 1). Let x - 5, 6, 7, . . . ,15, find function values, and connect the resulting points with a smooth curve. Then create a graph for the function that models the percentage of adult height attained by a girl who is x year.; old. g(x) - 62 + 351og(x - 4). let x - 5, 6, 7, . .. . 15, find function values, and connect the resulting points with a smooth curve. Group members should then isctL~s similarities and differences in the growth patterns for boys and girls based on the graphs.
