Question

Please give the right answer And reply only if u know the answer

Answer 1

Step-by-step explanation:

a²+1/a²=23

a²+1/a²+2=25

we know that,a²+b²+2ab=(a+b)²

(a+1/a)²=25

a+1/a=sq. 25=5

a³+1/a³=(a+1/a³=(a+1/a)(a²+1/a²‐ab)

as we know that a³+b³=(a+b)(a²+b²-ab)

a²+1/a³=5(23‐1)

a³+1/a³=5(22)
