Answer 1

10

a)

3³- 3²:(2⁶-2⁵-2⁴- 2³- 2²- 2¹- 2⁰) =

3³- 3²:(64 - 32 - 16 - 8 - 4 - 2 - 1) =

3³- 3²:(64 - 63) =

3³- 3²:1 = 3²· ( 3 - 1 ) = 3² · 2 = 9 · 2 = 18

Answer 2

$10) \\ \\ a) {3}^{3} - {3}^{2} : ( {2}^{6} - {2}^{5} - {2}^{4} - {2}^{3} - {2}^{2} - {2}^{1} - {2}^{0}) = \\ \\ {3}^{3} - {3}^{2} : (64 - 32 - 16 - 8 - 4 - 2 - 1) = \\ \\ 27 - 9 : 1 = \\ \\ 27 - 9 = \\ \\ 18$
