The minus negative 7 in the square root is throwing me off I dont understand if i should add the 7 because there are two negatives or if I should subtract a negative 7 and also the negative 7 squared it throwing me off  I'm confused about how I should count the negatives. Should I count it as -7^2 or (-7)^2? Thank you very much for your help.  </SPAN>\n" );
