IM 8.7.4 Practice: Dividing Powers of 10

① This example demonstrates the rules for dividing powers of 10, allowing students to explore the pattern of subtracting exponents through interactive input fields. ② Core mathematical concepts include the division law of exponents, exponent operations, scientific notation basics, and place value changes. ③ Construction highlights: It uses GeoGebra's Textfield command to create multiple input boxes (InputBox1, InputBox3, InputBox5, InputBox7, InputBox9) linked to objects f1 through f5, enabling dynamic user input and immediate feedback. ④ Suitable for 8th-grade students learning exponent rules, and useful as a classroom demonstration or self-paced practice tool to visualize the principle of subtracting exponents.
