Final answer:

To find dy/dx for x^4 + y^4 = 82 using implicit differentiation, differentiate both sides with respect to x and solve for dy/dx, resulting in dy/dx = -(x^3)/(y^3).

Step-by-step explanation:

The student is asking for assistance with finding dy/dx using implicit differentiation for the equation x^4 + y^4 = 82. To solve for dy/dx, we differentiate both sides of the equation with respect to x, which gives us 4x^3 + 4y^3(dy/dx) = 0. We can then solve for dy/dx by isolating it on one side of the equation. The resulting computation will be dy/dx = -(x^3)/(y^3). This equation signifies the slope of the tangent to the curve at any point (x, y) on the curve defined by the given equation.

To find dy/dx using the method of implicit differentiation, we start by differentiating both sides of the equation x^4 + y^4 = 82 with respect to x. The derivative of x^4 with respect to x is 4x^3, and the derivative of y^4 with respect to y is 4y^3 * dy/dx. Therefore, the equation becomes 4x^3 + 4y^3 * dy/dx = 0. Solving for dy/dx, we get dy/dx = -4x^3 / (4y^3) = -x^3 / y^3.
