Answer 2

a+1/a = 4

then,

                 (a+1/a)^3                  =  (a + 1/a)^3 + 3 * a * 1/a * (a + 1/a)                         a^3 + 1/a^3            =   (4)^3 + 3* (4)

                      a^3 + 1/a^3            =  64 + 12

a^3 + 1/a^3              =  76 (answer)

hope this is helpful to you !
