Question

30w^{2}x^{3}+48w^{3}+47w^{3}+9w^{3}–20w^{3}

Answer 1

Given the following:

`30w^2x^3+48w^3+47w^(3)+9w^(3)-20w^(3)`

Like terms are those terms which have same variable to the same power.

`30w^2x^3+84w^3`

Take
`6w^2` common from
`30w^2x^3` and
`84w^3`

then;

we have;

`6w^2(5x^3+14w)`

Therefore, the simplified form of
`30w^2x^3+48w^3+47w^(3)+9w^(3)-20w^(3)` is
`6w^2(5x^3+14w)`
