Question

(3x^-2y)*(8xy^-3) --- SOLVE

Answer 1

$(3x^2-2y)*( 8xy ^{-3} )$

Remove parentheses : (a) = a

$= (3x^2-2y) * 8xy ^{-3}$

$y^{-3}$

Apply  expoent rule

 $a ^{-b} = \frac{1}{a ^{b} }$

$= \frac{1}{y^3}$

$8x \frac{1}{y^3} (3x^2-2y)$

Multiply fractions:

$a* \frac{b}{c} = \frac{a*b}{c}$

$= \frac{8(3x^2-2y)}{y^3}$

hope this helps!
