Is a negative square root a real number
WebThe square roots of the number N are written as – N and + N which are read as “the negative square root of N ” and “the positive square root of N”. Properties All positive real numbers N have two square roots, written as – N and + N. If N is a positive real number, then n has two real values, with the same absolute value but with opposite signs. http://content.nroc.org/DevelopmentalMath/COURSE_TEXT2_RESOURCE/U16_L4_T1_text_final.html
