\(\frac{9\times8\times15}{6\times4\times15}\)

\(=\frac{3\times3\times4\times2\times15}{3\times2\times4\times15}\)

\(=\frac{3}{1}\)

\(=3\)

= 10800

a) Ta có: AM=MC=AC2AM=MC=AC2(M là trung điểm của AC)

AN=NB=AB2AN=NB=AB2(N là trung điểm của AB)

mà AC=AB(gt)

nên AM=MC=AN=NB

Xét ΔAMB và ΔANC có 

AM=AN(cmt)
