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

Try This!  Expanding 

For Questions 1-6, write in exponential form and simplify.

  1. The area of a square with side 3.
  2. The volume of a cube with side 5.
  3. \(2\cdot2\cdot2\cdot2\cdot2\)
  4. \(2\cdot2\cdot3\cdot3\cdot3\)
  5. The volume of a cube with side \(\dfrac12\) (express answer in simplified fraction form). 
  6. \(9\cdot x\cdot x \cdot x \cdot x\)

  7. Write an expression for the perimeter of a square with side 3. How is this different from the expression to find the area (Question 1)?
  8. Simplify each of the following and explain how they are different:

\(2x+2x+2x+2x+2x\)

\(2x\cdot 2x\cdot 2x\cdot 2x\cdot 2x\)

  1. Simplify the expressions \((-2)^3\) and \(3(-2)\) and show mathematically how they are different.
