This math topic focuses on practicing scientific notation, particularly dividing powers of ten with decimal points. It includes a series of problems where learners need to divide one power of ten by another, each presented as a fraction where both the numerator and the denominator are in scientific notation. Each question offers multiple choice answers, all formatted in scientific notation, challenging students to correctly perform the operations and identify the correct result. This exercise is part of an introductory unit on multiplication and division in scientific notation.
