How Do You Solve a Word Problem by Taking a Monomial to a Power?
Find the volume of a cube box whose sides have the length 2a2b. Write the solution as a monomial in simplest form.
Summary
- The cube's sides have the length '2a2b'
- A cube, by definition, has sides of equal lengths
- 'a' and 'b' are variables
- The volume of a cube is the 'cube' of one of it's lengths
- The 'cube of something' is just a fancy way of saying 'something to the 3rd power'
- We use the power of a product rule to distribute the exponent '3' to each factor in '2a2b'
- (a2)3 = a2 • 3 = a6
- 23 = 8
