The graphs of the equations 3x-20y-2=0 and 11x-5y +61=0 intersect at P(a,b). What is the value of (a² + b² − ab)/(a² − b²...
If a2+2 = 2a
then find a4 - a3 + 2a2 -2a+ 9 = ?
If a+1/a =9, then a5+1/a5 is equal to:
If x + 1/x = 5 then find out the value of x⁵ + 1/(x⁵)?
Evaluate (998)3 without multiplying directly.
If a + (1/a) = 2, then find the value of (a5 + a3 + 6)/(7a – 5).
If 125x3 - 64y3 = (Ax + By) (Dy2 - Cx2 + 20xy) , then the value of A + C - 2B + 3D is:
If (a + b + c) = 9, find (a – 4)3 + (b – 2)3 + ( c – 3)3 - 3(a – 4 ) (b – 2 ) (c – 3)?
