Question

[-1/20 X^4 Y^3] (-5x^7 y^2)

Answer 1

$(\frac{-1}{20}{x}^{4}{y}^{3})(-5{x}^{7}{y}^{2})$

$-\frac{1}{20}{x}^{4}{y}^{3}\times -5{x}^{7}{y}^{2}$

$-\frac{1\times {x}^{4}{y}^{3}\times -5{x}^{7}{y}^{2}}{20}$

$-\frac{-5{x}^{4}{x}^{7}{y}^{3}{y}^{2}}{20}$

$-\frac{-5{x}^{4+7}{y}^{3+2}}{20}$

$-\frac{-5{x}^{11}{y}^{3+2}}{20}$

$-\frac{-5{x}^{11}{y}^{5}}{20}$

$-(-\frac{5{x}^{11}{y}^{5}}{20})$

$\frac{5{x}^{11}{y}^{5}}{20}$

$-(-\frac{{x}^{11}{y}^{5}}{4})$

$\frac{{x}^{11}{y}^{5}}{4}$
