Calculate the total magnification of the microscope for the given combinations of objective and eyepiece.

For each combination, multiply the magnification of the objective by the magnification of the eyepiece: For 10x objective and 10x eyepiece: 10 * 10 = 100x For 10x objective and 15x eyepiece: 10 * 15 = 150x For 10x objective and 20x eyepiece: 10 * 20 = 200x ... and so on for each combination.
