Efectuati :
(-2XYZ⁴)²
(1,5XYla a 3)la a 3

Answer 1

$(-2XYZ ^{4} ) ^{2} =\ \textgreater \ (-2XYZ) ^{4*2} =\ \textgreater \ (-2XYZ) ^{6}$ numere negative la puteri pozitive sunt numere pozitive =>[tex]( 2XYZ) ^{6} =\ \textgreater \ 2XYZ*2XYZ* 2XYZ*2XYZ*2XYZ*2XYZ=\ \textgreater \ [/tex]$=\ \textgreater \ 12X ^{6} Y ^{6} Z ^{6}$
$(1,5XY^{3} ) ^{3} =\ \textgreater \ (1,5XY) ^{3*3} =\ \textgreater \ (1,5XY) ^{9} =\ \textgreater$[tex]1,5XY*1,5XY*1,5XY *1,5XY*1,5XY*1,5XY *1,5XY* [/tex]$1,5XY*1,5XY=\ \textgreater \ 13,5X^{9} Y ^{9}$
