 Question 102981: I am having a difficult time understanding rational, irrational and complex numbers. So far I have come up with (from my homework) 3-(-5)^1/2i as complex- is this correct? My question is what is (2)^1/2 + 2? I was thinking irrational but like I said I am having a difficult time with this. Thank you in advance for any help. Click here to see answer by scott8148(6628)

 Question 108912: Can someone PLEASE HELP me with this problem, I really do NOT understand any of this problem , if someone could please explain and help me with all these questions to this problem I would so much appreciate it. THANK YOU!!!! Every fraction has a decimal equivalent that__either terminates (for example, 1/4 = 0.25) or repeats (for example,2/9 = 0.2). (The line is above the 2 of the 0.2) Work with a group to discover which fractions have terminating decimals and which have repeating decimals. You may assume that the numerator of each fraction you consider is and focus your attention on the denominator. As you complete the table below, you will find that the key to this question lies with the prime factorization of the denominator. Prime Factorization Fraction Decimal Form Terminate? of the Denominator _______________________________________________________________________________ 1/2 1/3 1/4 1/5 1/6 1/7 1/8 1/9 1/10 1/11 1/12 State a general rule describing which fractions have decimal forms that terminate andwhich have decimal forms that repeat. Now test your rule on at least three new fractions. That is, be able to predict whether a fraction such as 1/25 or 1/30 has a terminating decimal or a repeating decimal. Then confirm your prediction.
