Question

Write 19 and 1/2 in radical form

Answer 1

you mean \[\Large 19^{1/2}\] right?

Answer 2

the 1/2 is an exponent

Answer 3

Yes what you said jim

Answer 4

so it's simply

\[\Large 19^{1/2} = \sqrt[2]{19} = \sqrt{19}\]

the index of '2' is not needed since square roots are by default radicals with index of 2

Answer 5

I'm using the rule

\[\LARGE x^{1/n} = \sqrt[n]{x}\]
