7-74.

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.

$6=a·b^0$
$24=a·b^2$
Hint (a):
Remember that b⁰ = 1.
Hint (a):
You can use this fact to make the first equation 6 = a, and then substitute 6 for a in the second equation.
Hint (a):
Solve for b.
24 = 6b²

$32=a·b^2$
$128=a·b^3$
Answer (b):
a = 2,
b = 4
