Question

Sa se calculeze:a) (x⁵y³)²:(x³y)³,rog cine stie sa ma ajute,

Answer 1

Explicație pas cu pas:

$a)( {x}^{5} {y}^{3}) ^{2} : ( {x}^{3}y)^{3} = \frac{( {x}^{5})^{2}( {y}^{3}) ^{2} }{( {x}^{3}y) ^{3} } = \frac{ {x}^{10} {y}^{6} }{( {x}^{3}) ^{3} {y}^{3} } = \frac{ {x}^{10} {y}^{6} }{ {x}^{9} {y}^{3} } = {x}^{10 - 9} {y}^{6 - 3} = {x}^{1} {y}^{3} = {xy}^{3}$
