@visitsameer said:Q4. If a=3+2rt2 Find (a^6+a^4+a^2+1)/a^3...answer is 204...... a=3+2rt2 and 1/a is 3-2rt2 .....now solveQ5. If x is real and x^4+(1/x^4) = 119 Find x - 1/xlet x-1/x = y then sqaure x^2+1/x^2 - 2=y^2 .....x^2+1/x^2 =y^2+2again square x^4 +1/x^4 +2 = y^2+4+2y ..........x^4 +1/x^4 =so y^2 +2y+2 =119y^2 +2y -117=0y^2 +13y-9y -117 =0Y= 9 or -13 answer
