Venn Diagram - Number System:
The number is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=e90f1afa4e96cfff3dbcf8fe286dae19.png\")
. Radicand is 7.
The square root of ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=230742aa05662420cfbb78593662a99b.png\")
is not a perfect square and
the decimal (![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=a73699adf6d979f154011d21020e3a91.png\")
) of the number is not repeating, so the number ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=e90f1afa4e96cfff3dbcf8fe286dae19.png\")
is an irrational number (I).
\§ Observe the Venn diagram:
\§ All irrational numbers (I) are real numbers \ \
\![\"\"](\"../../../userfiles/image/steps_images/solution.JPG\")
The number belongs to I, and R.
