Answer 1

Explicație pas cu pas:

3.

$( {3}^{8} \cdot {6}^{5} \cdot {5}^{7} + {3}^{ {2}^{3} } \cdot {3}^{5} \cdot {2}^{5}) : ({5}^{7} + {5}^{0}) =$

$= ( {3}^{8} \cdot {6}^{5} \cdot {5}^{7} + {3}^{8} \cdot {(3\cdot2)}^{5}) : ({5}^{7} + 1)$

$= ( {3}^{8} \cdot {6}^{5} \cdot {5}^{7} + {3}^{8} \cdot {6}^{5}) : ({5}^{7} + 1)$

$= ( {3}^{8} \cdot {6}^{5} \cdot ({5}^{7} + 1)) : ({5}^{7} + 1)$

$= ( {3}^{8} \cdot {6}^{5}) \cdot ({5}^{7} + 1) : ({5}^{7} + 1)$

$= \bf {3}^{8} \cdot {6}^{5}$

4.

${( {2}^{4} )}^{3} \cdot {( {2}^{3} )}^{3} \cdot {2}^{3} = {2}^{12} \cdot {2}^{9} \cdot {2}^{3} = \\ = {2}^{12 + 9 + 3} = \bf {2}^{24}$
