# EXPS 1 | Lesson 1 | Practice

Write each expression in expanded form and simplify.

1. $$(-2)^3(5^2)$$
2. $$\bigg(\dfrac34\bigg)^4(-2)^3$$
3. $$x^3y\cdot x^2y^2$$

1. Simplify the expressions $$(3x)^3$$ and $$3x^3$$ and show mathematically how they are different.
2. Explain why $$(2x)^3\neq3\cdot(2x)$$
