Answer 1

If you're not going to use your equation writer tools, then you should use parentheses so that your question is clearly stated and understood.

Put the radicand in parentheses.

Put the denominator in parentheses.

If one is inside the other, and that requires more than one set, so be it,

but the question will be clear, and your answers will come quicker...
