its less than 713.21 but greater than 5.2
[tex]\boxed{\bold{2240a^4u^{18}w^3x^4}}[/tex]
explanation:
remove parenthesis: [tex]\bold{\left(a\right)=a,\: -\left(-a\right)=a}[/tex]
= [tex]\bold{4u^9w^1\cdot \: 7x^4\cdot \: 4a^3w^2\cdot \: 8\cdot \frac{1}{2}a^1\cdot \: 5u^9}[/tex]
apply rule [tex]\bold{a^1=a}[/tex]
= [tex]\bold{4\cdot \: 7\cdot \: 4\cdot \: 8\cdot \: 5\cdot \frac{1}{2}a^3au^9u^9w^2wx^4}[/tex]
multiply fractions: [tex]\bold{\: a\cdot \frac{b}{c}=\frac{a\: \cdot \: b}{c}}[/tex]
= [tex]\bold{\frac{1\cdot \: 4u^9w\cdot \: 7x^4\cdot \: 4a^3w^2\cdot \: 8a\cdot \: 5u^9}{2}}[/tex]
[tex]\bold{1\cdot \: 4u^9w\cdot \: 7x^4\cdot \: 4a^3w^2\cdot \: 8a\cdot \: 5u^9: \ 4480x^4w^3a^4u^{18}}[/tex]
= [tex]\bold{\frac{4480a^4u^{18}w^3x^4}{2}}[/tex]
divide: [tex]\bold{\frac{4480}{2}=2240}[/tex]
= [tex]\bold{2240a^4u^{18}w^3x^4}[/tex]
mordancy.
it would be 6xy and -16xy.
