7-74.
  1. Find values of a and b that make each system of equations true (i.e., solve each system). Be sure to show your work or explain your thinking clearly. Homework Help ✎

    1. 6 = a · b0
      24 = a · b2

    2. 32 = a · b2
      128 = a · b3

Remember that b0 = 1.

You can use this fact to make the first equation 6 = a, and then substitute 6 for a in the second equation.

Solve for b.

24 = 6b2

a = 2,
b = 4
