Question

How do you factor the monomial `121abc^3` completely?

Answer 1

`121abc^2=11xx11xxaxxbxxcxxc`

Explanation:

We know that `121abc^3` is nothing but `121xxaxxbxxc^2`

i.e. `121xxaxxbxxcxxc`

Hence to factor given monomial, one just needs to factorize `121` and as `121=11xx11`

`121abc^2=11xx11xxaxxbxxcxxc`
