giúp mình gấp với

RÚT GỌN:

\(\frac{\text{4^5x9^4+2x6^9}}{\text{ }\text{2^10x3^8+6^8x20}}\)  

 

Answer 1

=\(\frac{2^{10}.3^8+12.6^8}{2^{10}.3^8+20.6^8}=\frac{2^{10}.3^8+12.2^8.3^8}{2^{10}.3^8+20.2^8.3^8}\)

\(=\frac{2^8.3^8\left(2^2+12\right)}{2^8.3^8\left(2^2+20\right)}=\frac{16}{24}=\frac{2}{3}\)
