Lời giải:
\(A=\frac{2^{12}.3^{10}+6^9.6.20}{-2^{12}.3^{12}-6^{11}}\)
\(=\frac{6^{10}.4+6^{10}.20}{-6^{12}-6^{11}}=\frac{6^{10}.24}{-6^{11}(6+1)}=\frac{24}{-42}=\frac{-4}{7}\)
\(\dfrac{-4^6.9^5-6^9.120}{-8^4.3^{12}-6^{11}}\)
\(\dfrac{4^6.9^5+6^9.120}{-8^4.3^{12}-6^{11}}\)
(4^6.9^5+6^9.120)/(-6^11-8^4.3^12)
4^6.9^5+6^9.120/-8^4.3^12-6^11
$\frac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}$
\(\frac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}\)
\(\frac{4^6.9^5^+6^9.120}{8^4.3^{12}-6^{11}}\)
Tính :
\(A=\frac{4^6.9^5+6^9.120}{-8^4.3^{12}-6^{11}}\)
\(B=\frac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}\)
TÍnh \(\frac{4^6.9^5+6^9.120}{-8^4.3^{12}+6^{11}}\)
