(49/16)^x × (64/343)^x-1 = 4/7

If a³ — b³ = 602 and a— b = 2, then find the value of( a² + b²)

If (x ² = 6x – 9), then find the value of [x³ + (x⁴/9)][5 - x³]

If √b + (1/√b) = 11, then find the value of b + (1/b).

If (r + s + t) = 12 and (rs + st + tr) = 60, then find the value of (r² + s² + t²).

If, ( a + b = 14 ) and ( a² + b² = 106 ), then find the value of (a³ + b³).

If (a + b) = 13 and ab = 18, find the value of (a² + b²).

If a – b – c = 0, then the value of (a² + b² + c²)/(b + ac) is:
