Question

Ajutorrrrrrrrrrrrrr!!

Answer 1

[tex]a = \frac{0.2^3*10^4}{324} : \frac{8^3*15}{12^5}\\\\ a = \frac{0.008*10000}{324} : \frac{2^9*15}{2^{10}*3^5}\\\\ a = \frac{80}{324} : \frac{15}{2*3^5}\\\\ a = \frac{20}{81} : \frac{5}{2*3^4}\\\\ a = \frac{20}{81} * \frac{2*3^4}{5}\\\\ a = \frac{40*3^4}{405}\\\\ a = \frac{3240}{405}\\\\ a = \frac{648}{81}\\\\ a = 8[/tex]

Acum b :)

[tex]b = 23.7 - 3^2 + 5.9:0.59-2.1:3\\ b = 23.7 - 9 + 10-0.7\\ b = 23 +1\\ b = 24[/tex]

deci cmmdc-ul lor e 8
