The correct answers are:

2sqrt10

40^1/2

Explanation:

I got it right on the Plato test.

Answer 2

`40 {}^{ (1)/(2) }`

Explanation:

The last one is also the answer

Using the rational exponet rule,

`\sqrt[n]{ {x}^(m) } = x {}^{ (m)/(n) }`

Using this number,

`√(40)`

40 is the base so it will stay same. Remember this is a square root sign so our nth root is 2 so our denominator if the rational exponet is 2.

`40 {}^(1) = 40`

so our numerator is 1 so

`40 {}^{ (1)/(2) }`
