hIn which year was the Battle of Plassey fought?

What is the value of (a² + b²+4c²- ab-2bc-2ca) (a + b+2c):

Simplify the expression:
3x + 5y - [(7x + 3y) - (2x + y) + 4y] - x

If x, y, z are the three factors of a ³– 7a – 6, then value of x + y + z will be

Which of the following statements is correct?

I. If x = 12, y = –2 and z = –10, then x³ + y³

+ z³ = 720

If p = 25 - q - r and pq + r(q + p) = 189, then find the value of (p² + q² + r²).

If   a ² + b ² + c ² = 40 & ab + bc + ca = 12 then  a + b+ c = ?

If x³ + y³ = 9 and x + y=3 then the value of x⁴ + y⁴ is:

If x/y = 5/3, Find (x+y)/(x-y)?

If x = √7 + √6 and y = √7 - √6 , then the value of is (x² + y²)/(x³ + y³).
