Consider the two equations below. Explain completely the similarities and

differences in how you would solve each equation. Be clear and complete.

3* = 12 and x3 = 12

Here, the given equations,

and

Similarity: In both equations there is only one variable ( i.e. x)

Difference: is an exponential equation while is a polynomial equation.

Now, when we solve an exponential equation we take log in both sides of the equation as follows:

      ( ∵ )

Hence, the solution of the equation is .

While, when we solve a polynomial we find the roots as follows:

By zero product property,

or

If , then

If ,

Then, by quadratic formula,

Hence, the solutions of the equation are ,    and   .
