ATQ,
If (x2 + y2 + z2 - 4x + 6y + 13) = 0, then find the value of (x + y + z).
If 3x + (1/3x) = 8 then find 27x3 + (1/27x3) = ?
Evaluate (998)3 without multiplying directly.
If x = 8.15, y = 9.06 and z = –17.21, then the value of x³ + y³ + z³ – 3xyz is:
4x +4y =20 and 4x+y =64 then find the value of 4x-y +4y-x.
if a2 + b2 + c2 = 2(4a -5b -6c)-77 , then a-b-c = ?
? + (35)² = (130)² - (45)² - 2850
If x = √7 + √6 and y = √7 - √6 , then the value of is (x2 + y2)/(x3 + y3).
