Explanation:
Detailed explanation-1: -Grades 1-8 typically will buy a monocular compound microscope with 3 objective lenses: 4x, 10x, 40x for maximum total magnification of 400x.
Detailed explanation-2: -4x is a common magnification for scanning objectives and, when combined with the magnification power of a 10x eyepiece lens, a 4x scanning objective lens gives a total magnification of 40x.
Detailed explanation-3: -For example, optical (light) microscopes are usually equipped with four objectives: 4x and 10x are low power objectives; 40x and 100 are powerful ones. The total magnification (received with 10x eyepiece) of less than 400x characterizes the microscope as a low-powered model; more than 400x as a powerful one.
