The average of three numbers a, b and c is 2 more than c. The average of a and b is 48. If d is 10 less than c, then the average of c and d is:

If (x + y) = 35, then find the value of (x - 10)⁶ + (y - 25)⁶.

If (x + y) = 6 and (x² + y²) = 20, then the value of (x – y)² is equal to:

If x^2a = y^2b =z^2c ≠ 0 and x² = yz, then the value of (ab + bc + ca) /bc is :

If n = 3 + √2, then find the value of (n + 1/n)².

If y + 1/y = 2 then find y¹¹⁷ + 1/(y¹¹⁷)

If (a + b) = 1 and (1/a) – 2b = 5/a then find the value of a² + b².

If  a²+2 = 2a

then find a⁴ - a³ + 2a² -2a+ 9 = ?

Suppose xy = -15 and (x² + y²) = 34, then determine the value of (x – y).
