Multiply and completely simplify the expression.  Enter the answer in standard form in the box below. 2×21+x2{“version”:”1.1″,”math”:”2×21+x2″} Some items, like this one, require a longer, written response.  There are two options for you to enter your answer.  You can choose either method.  The key is to clearly communicate your response to me.  If I can understand it, I will grade it. The built-in Equation tool allows you to enter “nice” looking mathematical expressions.  Click the + dropdown, then Equation, then Graphical Equation.  This opens a set of templates.  The first tab contains templates for exponents, fractions, radicals, and grouping symbols.  When satisfied with your response, click Insert.  You may edit your response any time prior to submitting your test by selecting it and re-opening the Equation tool.  Take some time on this practice test to explore using this tool, since the actual test is timed. You may also use keyboard symbols or type an accurate description of your written response.  For example, to enter the expression xyx2y3 {“version”:”1.1″,”math”:”xyx2y3 ”}, you can type “the absolute value of xy times the square root of x squared times y cubed,” or something like that.  It would also be fine to type |xy|*sqrt(x^2y^3).  Again, if I can understand it, I’ll score it. Finally, I strongly recommend sending me your work after the test.  I can’t allow you to use your phone to take pictures or videos during the test, but you may scan/send your work to me by e-mail after submitting your test.  If I can see your written work (not just an answer, but how you got it), I’m able to assess partial credit for an incorrect result.  If you only submit an incorrect answer, I have nothing else to assess.  It is to your great advantage to SHOW WORK, even though this is an online exam.
