Answer 1

Răspuns:

$\bf a) \: {2}^{3} + {2}^{2} + {2}^{2000} \cdot( {3}^{2} - {2}^{3} - {5}^{0}) =$

$\bf {2}^{3}+{2}^{2}+{2}^{2000} \cdot( 9 - 8-1) =$

$\bf 8+4+{2}^{2000} \cdot( 1-1) =$

$\bf 8+4+{2}^{2000} \cdot0 =$

$\bf 12+0 = \pink{ \underline{ \: 12 \: }}$

$\bf b) \: (5 \cdot13 - 3^{2}):2^{3} + 672 : 16 =$

$\bf (65 - 9):8 + 672 : 16 =$

$\bf 56:8 + 42=$

$\bf 7 + 42= \red{ \underline{ \: 49 \: }}$
