Kết quả của phép tính: 4^5.9^4–2.6^9/2^10.3^8 6^8.20 .

Trả lời

$\frac{4^5{.9}^4-{2.6}^9}{2^{10}{.3}^8+6^8.20}=\frac{{\left(2^2\right)}^5.{\left(3^2\right)}^4-{2.2}^9{.3}^9}{2^{10}{.3}^8+2^8{.3}^8{.2}^2.5}=\frac{2^{10}{.3}^8-2^{10}{.3}^8.3}{2^{10}{.3}^8+2^{10}{.3}^8.5}=\frac{2^{10}{.3}^8(1-3)}{2^{10}{.3}^8(1+5)}=-\frac{2}{6}=-\frac{1}{3}$
