Question

How do you simplify `sqrt74`?

Answer 1

You can't.

Explanation:

When we simplify radicals (anything with a root sign), we try to only write only whole numbers (no fractions, no long decimals). For this to happen, the number under the root sign has to have a factor which is a square number. Examples include:
`50`, which has a factor 25, which is `5^2`
`162`, which has a factor 81, which is `9^2`

Unfortunately, 74 doesn't have a factor which is a square number (74's factors are 2 and 37), so we can't proceed with simplifying it.
