Dau 40 puncte pentru raspunsul corect: utilizind proprietatile puterii cu exponent intreg efectuati operatiile
[tex] a) x^{4}* x^{-2} 
[/tex]
$b) \frac{a ^{6} }{a ^{-4} }$$h) (\frac{c -^{2} }{a -^{1} } ) ^{-3}$

Answer 1

a) x^(4-2)=x²

b) (a^6): a^(-4) = a^ [6-(-4)]=a^(6+4)=a^10

[c^(-2)^(-3)]/[(a^(-1)]^(-3)= c^[(-2)*(-3)]/ a^[(-1)*(-3)]= (c^6)/a³
