The correct answer is D
If x =7+4√3. then find the value of x +1/ x
((99.9 - 20.9)² + (99.9 + 20.9)² )/(99.9 x 99.9 + 20.9 x 20.9) = ?
...`25(2/3)+11(1/9)+16(4/5)xx6(5/12)` = ? -`632/45`
when x =4 and y =-6 then find the value of 27x³ +58x²y +31xy² +8y³?
when x =5 and y =-7 then find the value of 27x³ +58x²y +31xy² +8y³?
If 9x2 + 16y2 = 24xy, then find the ratio of ‘x’ and ‘y’, respectively.
If x = 35, then the value of x5 - 36x4 + 36x3 - 36x2 + 36x - 1 is
