Answer 2

a.  2⁵-2⁴-2³-2²-2-1=32-16-8-4-2-1=1

b.  3⁵- 2.3⁴ -2.3³-2.3²-2.3-2= 243-2x (3⁴-3³-3²-3-1) = 243 - 2 x(81-27-9-3-1)=

     =243 -2x41 = 243 - 82 = 161

c.  4⁵-3.4⁴-3.4³-3.4²-3.4-3 = 4⁵- 3 (4⁴-4³-4²-4-1) = 4⁵- 3.(256-64-16-4-1)

    = 1024 - 3.171 = 1024-513=511

d,  5⁵-4.5⁴-4.5³-4.5²-4.5-4 = 5⁵- 4 (5⁴-5³-5²-5-1)= 3125-4.(625-125-25-5-1)=

     =3125-4.469 = 3125-1876 = 1249
