Finding Triangle Vertices
the problem, and all three students are involved in that experiment. Dana, by line 6, is ready for a different approach. In line 9, Dana suggests using the area formula not to check a point they pick at random, but to find the height of the triangle. At this stage, Dana, too, is …

mathpractices.edc.orgextending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents. For example, we define 51/3 to be the cube root of 5 because we want (51/3)3 = 5(1/3)3 to hold, so (51/3)3 must equal 5. Math Topic Keywords: exponents, rational exponents, rules of exponents
