[Hoàng Thu Huyền]

Tính giá trị của các biểu thức:

G=21^2.14.125/35^5.6

H= 45^3.20^4.18^2/180^5

HELP ME

Answer 1

[Nguyemminhanh]

G=(21².14.125):35⁵.6

=\(\frac{\left(3.7\right)^2.7.2.5^{^3}}{\left(7.5\right)^5.2.3}\)=\(\frac{3^2.7^2.7.5^3}{7^5.5^5.3}\)=\(\frac{3}{7^2.5^2}\)=\(\frac{3}{49.25}\)=\(\frac{3}{1225}\)

Answer 2

[KAl(SO4)2·12H2O]

\(G=\frac{21^2.14.125}{35^5.6}\)

\(G=\frac{\left(3.7\right)^2.7.2.5^3}{\left(7.5\right)^5.2.3}=\frac{3}{7^2.5^2}=\frac{3}{49.25}=\frac{3}{1225}\)
