Which of these statements are true about radicals exponents? 1. The nth of a can be written as and as [tex]a {}^{ \frac{1}{n} } [/tex] [tex] \sqrt[n]{a} [/tex] 2. The notation a1/2 is rational exponent notation for the square root of a
3. [tex]a { }^{ \frac{p}{q} } = \sqrt[p]{a {}^{q} } = ( \sqrt[p]{a} ) {}^{q} [/tex] 4. The notation is radical notation for the square root of a [tex] \sqrt{a {}^{n} } [/tex]
