Answer:
Hiii,
Hiii,a + 1/a = 3
Hiii,a + 1/a = 3=>(a + 1/a)^ = 3^2
Hiii,a + 1/a = 3=>(a + 1/a)^ = 3^2=>a^2 + 2. a. 1/a + 1/a^2 = 9
Hiii,a + 1/a = 3=>(a + 1/a)^ = 3^2=>a^2 + 2. a. 1/a + 1/a^2 = 9=>a^2 + 2 + 1/a^2 = 9
Hiii,a + 1/a = 3=>(a + 1/a)^ = 3^2=>a^2 + 2. a. 1/a + 1/a^2 = 9=>a^2 + 2 + 1/a^2 = 9=> a^2 + 1/a^2 = 9-2 = 7
hope it will help you.......❣️
