Question

 E2. Sa se scrie ca puteri cu exponent rational numerele : 

√7; ∛27; ∛0,008; √3la a 7 ; ∛-(0,001) la a 4 ; √(0,0225) la -1 ; √ala a 6 x²,a >0,x>0 

Answer 1

$\sqrt{7}= 7^{ \frac{1}{2} }; \sqrt[3]{27}=3; \sqrt[3]{0,008}=0,2; \sqrt{3^7}= 3^{ \frac{7}{2} }; \sqrt[3]{-0,001}^4= 10^{-4}; \\ \sqrt{0,0225}=0,15$
