Answer:
Given the following:
[tex]30w^2x^3+48w^3+47w^{3}+9w^{3}-20w^{3}[/tex]
Like terms are those terms which have same variable to the same power.
[tex]30w^2x^3+84w^3[/tex]
Take [tex]6w^2[/tex] common from [tex]30w^2x^3[/tex] and [tex]84w^3[/tex]
then;
we have;
[tex]6w^2(5x^3+14w)[/tex]
Therefore, the simplified form of [tex]30w^2x^3+48w^3+47w^{3}+9w^{3}-20w^{3}[/tex] is [tex]6w^2(5x^3+14w)[/tex]
