The pronoun "its" is incorrect because it is used for objects or animals when the gender is not specified. Since "man" refers to a male person, the correct possessive pronoun should be "his." Therefore, the sentence should read: "The man was satisfied after having his lunch."
If x + y + z = 7, x² + y² + z² = 85 and x³ + y³+ z³ = 842, then the value of√3 xyz is:
...If x + y + z = 6, and x3 + y3 + z3 = 36, xyz = 6 then find (xy +yz + zx)?
[a/(2a² + 5a + 2)] = 1/6 , then find the value of (a+1)/a ?
If a² + c² + 17 = 2(a - 8b - 2c²), then what is the value of (a³ + b³ + c³)?
If x = 8.15, y = 9.06 and z = –17.21, then the value of x³ + y³ + z³ – 3xyz is:
(408 × 680)÷(20% of 680) = (250 × 260)÷ 10 + ? – 4500
