Q: - A, B, C are real values such that A+B+C=2, A2 +B2+C2 = 6 and A3+B3+C3 =,
then find the value of A4+B4+C4?

 

a) 6                b) 12                    c) 18                            d) 24

here inadequate data A3+B3+C3 =, value not given but i think

value of A4+B4+C4=18

because A+B+C=2+1-1=2

A2 +B2+C2 =4+1+1=6

A3+B3+C3 =8+1-1=8

A4+B4+C4=16+1+1=18
