Question

Efectuați: a) [(-5/3)^6]^3÷ (-5/3)^15 vă rog!​

Answer 1

Răspuns:

$\red{ \bf \bigg(- \dfrac{5}{3} \bigg ) ^{3}}$

Explicație pas cu pas:

$\bf \bigg[ \bigg(- \dfrac{5}{3} \bigg )^6 \bigg]^3 : \bigg(- \dfrac{5}{3} \bigg )^{15} = \bigg(- \dfrac{5}{3} \bigg ) ^{6 \cdot 3} : \bigg(- \dfrac{5}{3} \bigg )^{15} =$

$\bf \bigg(- \dfrac{5}{3} \bigg ) ^{18} : \bigg(- \dfrac{5}{3} \bigg )^{15} = \bigg(- \dfrac{5}{3} \bigg ) ^{18 - 15} = \red{\boxed{ \bf \bigg(- \dfrac{5}{3} \bigg ) ^{3}}}$
