M sorry man ur pickup way of questions is not correct....but u try to do .. thanks
X^2 +1/x^2. = 3. Then x^3 + 1/ x^ 3. =?
My bad , language was confusing
Don't worry...if I can do then plzzz solve this question these committed by me
Simple x^2+ 1/x^2 = 3 which means x+1/x = root 5
Now x^3+ 1/x^3 = (x+1/x) (x sq +1/xsq -1) = root5 * 2
Answr 2root5
Now x^3+ 1/x^3 = (x+1/x) (x sq +1/xsq -1) = root5 * 2
Answr 2root5
Thank you so much....
Now your answer is correct... again thanks to help me
