Interval and radius of convergence Determine the radius of convergence of the following power series. Then test the endpoints to determine the interval of convergence.

Solution 9EStep 1:Given that Step2:To findDetermine the radius of convergence of the following power series. Then test the endpoints to determine the interval of convergence.Step3The root test needs to be used to determine the radius and interval of convergence So,==r<1-3
