in order to raise an exponential term to a negative power, take the of the base and change the sign of the exponent

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

In the diagram below de and ed are tangent to 0 which expression gives the measure of def

Which of the following is most likely the next step in the series
