It's the same as if you have anything else in the denominator. You can multiply both sides by the squared variable. Example (using "^" for "power"):
a = 1 / b^2
Multiply both sides by b^2:
Step 1: a b^2 = b^2 / b^2
Step 2: a b^2 = 1
Please use the correct terminology first. Replace "formula" with "equation" and it will seem more logical. But to answer your question, just subtract it from both sides and it should come out on the other side as the same squared variable, although now it is negative.
Look for points where the denominator is equal to zero. In other words, solve the equation: denominator = 0
You CAN have a variable in the denominator 1/x=1 is a simple example. The answer is x=1. The other is 10/x=2 x=5.
Algebraically manipulate the equation until you have the indicated variable on one side of the equation and all of the other factors on the other side.
In an equation b or any other letters usually denotes the unknown variable.

rRestate the equation as A = 3.14r2.The independent variable is the one you are given - in this case, 'r'.The dependent variable is the one you have to work out (it depends on the other variable). In this case, A.

isolation of the variable means to get the variable on one side of the equation and the integers on the other side
The fourth equation of motion states that the final velocity squared is equal to the initial velocity squared plus two times the acceleration times the displacement. It is derived from the equations of motion for constant acceleration and is used to calculate an unknown variable when the other three are known.
1. Elimination: Select two equations and a variable to eliminate. Multiply each equation by the coefficient if that variable in the other equation. If the signs of the coefficient for that variable in the resulting equations are the same then subtract one new equation from the other. If they have opposite signs then add them. You will now have an equation without that variable. Repeat will other pairs and you will end up with one fewer equation and one fewer variable. Repeat this process: after each round you will have one fewer equation and one fewer variable. Keep going until you are left with one equation in one variable. Solve that. Then work backwards solving for the other variables.2. Substitution: Select a equation and a variable. Make that variable the subject of the equation. The right hand side of this equation is an expression for that variable. Substitute this expression for the variable is each of the other equations. Again, one fewer equation in one fewer variable. Continue until you are left with one equation in one variable. Solve that. Then work backwards solving for the other variables.3. Matrix inversion: If A is the nxn matrix of coefficients, X is the nx1 [column] matrix of variables and B is the nx1 matrix of the equation constants, then X = A^-1*B where A^-1 is the inverse of matrix A.
In an equation b or any other letters usually denotes the unknown variable.
You solve the equation the same way as you would any other equation. Whether the variable is a fraction or otherwise will only become clear once you solve the equation. In other words, you don't initially KNOW whether the solution will be a fraction or not.
