Question

Which expression is another way to write 3 radical 125 x^4?

Answer 1

The given expression is

`3√(125x^4)`

We have to write it in a different way and for that, we have to check the factors of 125 and x^4 .

And factors of 125 are 25 and 5.

`3√(25*5*(x^2)^2)`

Radical 25 equals to 5 and radical
`x^4` is
`x^2`.

So we will get

`3*5x^2 √(5) = 15x^2 √(5)`

And that's the another way to write the given expression .
