Question

X +1/x=6 then x square +1/x square =?

Answer 1

Step-by-step explanation:

X-1/x = 6. Squaring on both sides (x-1/x)²=6² x²+1/x²-2=36 x²+1/x²=38. Now again squaring on both sides (x²+1/x²)²= 38². ans

Answer 2

Answer:

$( {x + 1 \div x})^{2} = {x}^{2} + 1 \div {x}^{2} + + 2 \\ {6}^{2} = {x}^{2} + 1 \div {x}^{2} + 2 \\ {x}^{2} + 1 \div {x}^{2} = 34$
