Question

Simplify 3√-125n^12 A) -5n^9 B) -5n4 C) 5n4

Answer 1

the answer is B) i had the same question and it was right

Explanation:

Answer 2

For this case, we must simplify the following expression:

`\sqrt [3] {- 125n ^ {12}}`

By definition of properties of roots and powers we have:

`\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}`

In addition, we have to:

`\sqrt [3] {- 125} = - 5`

So:

`\sqrt [3]{- 125n ^ {12}} = - 5n^ {\frac {12} {3}} = - 5n^ 4`

Answer:

`-5n ^ 4`

Option B
