Powerful Tens: a Practice Task M3U3D3 Powerful Tens: a Practice Task Objective: For exponential models, express as a logarithm the solution to abct = d where a, c, and d are numbers and the base b is 2, 10, or e; evaluate the logarithm using technology. Essential Question: How can we use tables, graphs, and algebraic reasoning to help us solve exponential and logarithmic equations?

Assign p. 15-17 #1-3, 7-12 in card pairs Begin by reminding students about the process required to evaluate functions. Assign p. 15-17 #1-3, 7-12 in card pairs Begin exploration by discussing: 94.87 = 3(10x) Evaluate functions using tables, equations, diagrams, and graphs *In this task they will be using tables and graphs to work in reverse, finding the x value for a given y. Before checking assignment, discuss: 3 = log(x+3)

Then discuss the graph in #4: y = 10-x Check CW: Then discuss the graph in #4: y = 10-x Ask students to solve y = 10-x algebraically. 40 = 10-x log (40) = log (10-x) 1.602 = -x -1.602 = x

Check entire assignment using document camera. Exit Ticket: Find the solution to each equation. 1] 50 = 5 (10x-1) 2] 102x+1 = 1255
