Question

Which of these statements are true about radicals exponents?

1. The nth of a can be written as and as

`a {}^{ (1)/(n) }`

`\sqrt[n]{a}`
2. The notation a1/2 is rational exponent notation for the square root of a

3.

`a { }^{ (p)/(q) } = \sqrt[p]{a {}^(q) } = ( \sqrt[p]{a} ) {}^(q)`
4. The notation is radical notation for the square root of a

`\sqrt{a {}^(n) }`

5.

`a {}^{ (1)/(n) } = \sqrt{a {}^(n) }`
