2) (1/3)⁴ . (-9/2)⁶

3) (-13/8)³ (-32/13)⁴

Answer 1

[Minh Ánh]

1/ \(=-\frac{64}{27}.\frac{243}{32}\)

\(=-\frac{243}{16}\)

2/ \(=\frac{1}{81}.\frac{5361441}{64}\)

\(=\frac{6561}{64}\)

3/ \(=-\frac{2197}{512}.36,71356045\)

\(=-\frac{2048}{13}\)

tíc mình nha

Answer 2

[Nguyễn Phương Trung]

1\(\left(-\frac{4}{3}\right)^3.\left(\frac{9}{16}\right)^5=-\frac{2187}{16384}\)

2\(\left(\frac{1}{3}\right)^4.\left(-\frac{9}{2}\right)^6=\frac{6561}{64}\)

3\(\left(-\frac{13}{8}\right)^3.\left(-\frac{32}{13}\right)^4=-41,00457607\)
