\(\frac{2.2^{12}.3^6+2^2.2^9.3^9}{2^7.2^7.3^7.2^4.5.3^8}\)
\(=\frac{2^{13}.3^6+2^{11}.3^{^9}}{2^{18}.3^{15}.5}\)
\(=\frac{2^{11}.3^6\left(2^2+3^3\right)}{2^{11}.3^6.2^6.3^4.5}\)
\(=\frac{35}{2^6.3^4.5}\)
\(\dfrac{2.8^4.27^2+4.6^9}{2^7.6^7+2^7.40.9^4}\)
Tính A= \(\frac{2.8^4.27^2+4.6^9}{2^7.6^7+2^7.40.9^4}\)
a) Tính:
A = \(\dfrac{2.8^4.27^2+4.6^9}{2^7.6^7+2^7.40.9^4}\)
