Algebra.Com's Answer #763416 by Theo(13342)![]() ![]() You can put this solution on YOUR website! sqrt(-25) = sqrt(25 * -1) = sqrt(25) * sqrt(-1) = 5 * i = 5i.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "i is equal to sqrt(-1).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the solution is complex. \n" ); document.write( "a complex number has a real part and an imaginary part. \n" ); document.write( "the general form oa a complex number is a + bi. \n" ); document.write( "this solution how no real part. \n" ); document.write( "it only has an imaginary part. \n" ); document.write( "the general form of this solution would be 0 + 5i. \n" ); document.write( "this simplifies to 5i.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "if you are just looking for a real solution, then there is no solution.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "here's a reference on complex numbers you might find informative.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "https://www.mathsisfun.com/numbers/complex-numbers.html\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
