Question

Simplifique: (x2*x3)4=? (x3*x3)6=? (x5÷x3)4=? [(x2*x)3]2=? (x-4*x5)4=? {[(x5*x-7)2]3}°=? Me ajudem : faltei na aula perdi a explicação

Answer 1

$( x^{2} . x^{3} ) ^{4} = ( x^{2+3}) ^{4} = ( x^{5} ) ^{4} = x^{5.4}= \boxed{ x^{20} }$



$( \frac{ x^{5} }{ x^{3} } ) ^{4} =( x^{5-3} ) ^{4} = (x^{2}) ^{4} =\boxed{ x^{8} }$



$\{[( x^{5}. x^{-7} )^{2} ] ^{3} \} ^{0} =\{[ (x^{5-7}) ^{2} ] ^{3} \} ^{0} =\{[ x^{-2.2} ] ^{3}\} ^{0} =\{ x^{-4.3} \}^{0} = x^{-12.0} = x^{0}=\boxed{1}$
