Question

b=2002^4-2001x2002^3-2001x2002^2-2001x2002
Cat este b?

Answer 1

b=2002⁴-2001 × 2002³- 2001 × 2002²- 2001×2002

b=2002³(2002-2001)-2001×2002(2002+1)

b=2002³-2001×2002×2003

b=2002(2002²-2001×2003)

b=2002[2002²-2001(2002+1)]

b=2002(2002²-2001×2002-2001)

b=2002[2002(2002-2001)-2001]

b=2002(2002-2001)

n=2002×1

b=2002
