Calculate 22009-22008 using factorization, the result is () A.2 B.1 C.2008 D.-1

Calculate 22009-22008 using factorization, the result is () A.2 B.1 C.2008 D.-1

22009-22008
=22008(2-1)
=22008.
Therefore, C.

The power of 2009 of (-2)+ the power of 2008 of 3×(-2) equals?

Original equation =(-2)×(-2)2008 power +3×(-2)2008 power
2008 Power of =[(-2)+3]×(-2)
=2008 Power of 1×(-2)
2008 Power of =(-2)
=2008 Power of 2
Is that okay?
