Solve the following systems of equations. In other words, find values of a and b that make each system true. Be sure to show your work or explain your thinking clearly. Homework Help ✎

  1. 3 = a · b0
    75 = a · b2

  2. 18 = a · b2
    54 = a · b3

Anything to the zero power is 1, so a = 3.

Solve for a in the first equation. Then use substitution.

b = 3
