Anything that has an equal sign is an equation. So we've already eliminated A) from the list. Remember a linear equation is in the form Ax%2BBy=C. Notice how there are no exponents here. Since this expression has an exponent, the equation is nonlinear which means we can eliminate B). So the answer must be C).
