# EXPS 1 | Lesson 1 | Try This! (Expanding) Solutions

1. $$3^2 ~; ~9$$
2. $$5^3~ ; ~ 125$$
3. $$2^5~ ;~ 32$$
4. $$2^2\cdot3^3~ ; ~108$$
5. $$\bigg(\dfrac12\bigg)^3=\dfrac18$$
6. $$9x^4$$
7. The perimeter is $$3+3+3+3$$ or $$4\cdot3=12$$. The area is $$3\cdot3$$ or $$3^2=9$$. For perimeter you add four “3’s” or multiply 3 by 4, and for area, you multiply “3” by itself or square 3.
8. $$5\cdot 2x$$ or $$10x$$$$(2x)^5$$  or  $$32x^5$$
9. $$(-2)^3=(-2)\cdot (-2)\cdot (-2)=-8$$ and $$3(-2)=(-2)+(-2)+(-2)=-6$$
