To determine which of the given numbers are irrational, we need to understand the definition of irrational numbers. An irrational number is a number that cannot be expressed as a fraction of two integers. This means that irrational numbers are non-ter
If n and p are different positive prime numbers, which of the integers n4, p2, and np has (have) exactly 4 positive divisors ?() A.n4only B.p3only C.nponly D.n4andnp E.p3andnp 答案 E [解析] 因为n和p是互不相同的质数,所以根据质因子求解公式可得n4和p3。的因子数分别为4+1=5个和...

Examples of numbers that are not integers are: -1.43, 1 3/4, 3.14, . Is a positive integer? All the numbers we use for counting are positive integers. Positive integers are actually part of a larger group of numbers called integers. Integers are all the whole numbers, both positive and...
1、three positive integers(正整数)have a sum of 28.The greatest possible product that these integers can have is___.2、two numbers are in the ratio 2:3.when 4 is added to each number the ratio changes to 5:7.The sum of two orginal numbers is___.3、Did you...
Because n and m are both natural numbers, the sum of n and m is another natural number, n + m. Natural numbers are a subset of integers, integers are a subset of rational numbers, rational numbers are a subset of real numbers, and real numbers are a subset of complex numbers. Therefo...
For example,A ={xlχ=all even numbers>0}. integer Any whole number, whether negarive, positive,or zero.For example,-5,-4,-3,-2,-1,0, 1,2,3,4,5,…are all integers. intercept The point on a Cartesian graph where a line crosses an axis. If the line crosses the x-axis it ...
All the integers are divsible by 8 except 100.If the four consecutive odd integers are a,a+2,a+4 and a+6, the sum is 4a+12, and 4a+12 divided by 4 gives a+3. This means that a+3 must be even. The only integer that does not give an even integer when divided by 4 is ...
