Question

find the product of (5/9ab)(9/7bc)(-7/5ca)​

Answer 1

$Product \: of \: \Big(\frac{5}{9} ab \Big) \Big(\frac{9}{7} bc\Big) \Big(\frac{-7}{5} ca \Big)$

$= \frac{5}{9} \times \frac{9}{7} \times \Big(\frac{-7}{5} \Big) \times a \times a \times b \times b \times c \times c$

$= - a^{2} b^{2} c^{2}$

Therefore.,

$\red{Product \: of \: \Big(\frac{5}{9} ab \Big) \Big(\frac{9}{7} bc\Big) \Big(\frac{-7}{5} ca \Big) }$

$\green { = - a^{2} b^{2} c^{2} }$
