Find the radius of convergence of the power series.(If you need to use infinity or -INFINIFY, respectively Find the radius of convergence of the power series. (If you need to use infinity or -infinity, enter INFINITY or -INFINITY, respectively.)

Solution

Hi, (A) The radius is 1, because the series convergences with numbers less than 1 (B) The radius is 8, because the series convergences with numbers less than 8 Hope this help
