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.

$3=a·b^0$
$75=a·b^2$
Hint (a):
What is $b^0$ ?
More Help (a):
Use the value of $a$ from the first equation to solve for $b$ in the second equation.
