Question 1178303
<br>
Don't use the "√" symbol in your posts.  We can't tell whether the expression is<br>
{{{sqrt(x^2+7+5)}}} or {{{sqrt(x^2+7)+5}}} or {{{sqrt(x^2)+7+5}}}<br>
Evaluating any of those expressions at x=3 does not yield any of the answer choices.  Have you shown the expression correctly?<br>
Re-post, making sure you correctly show the correct expression.<br>
