Question

Whats the radical of 128

Answer 1

Answer:
`8√(2)`

Step-by-step explanation: find what numbers multiply to give you 128 (try to make sure that only one of the numbers is a perfect square). In this case it is 64 * 2. Then take the square root of 64 and 2.
`√(64) \ \ * \ √(2)`

you will be left with 8 *
`\sqrt{2` which would be written as
`8√(2)`.
