Question 118841


{{{((xy^9)/(3y^-2))*((-7y)/(21x^5))}}} Start with the given expression



{{{((xy^9)*(-7y))/((3y^-2)*(21x^5))}}} Combine the fractions



{{{(-7xy^10)/(63x^5y^-2)}}} Multiply the numerators and denominators by adding the exponents



{{{(-1/9)x^-4y^12}}} Divide




So {{{((xy^9)/(3y^-2))*((-7y)/(21x^5))}}} simplifies to {{{(-1/9)x^-4y^12}}}


In other words, {{{((xy^9)/(3y^-2))*((-7y)/(21x^5))=(-1/9)x^-4y^12}}}
