Do the Math!

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 \((2x)^3\neq3\cdot(2x)\)
