Example Question #1 : Ged Math
Express 
Each digit of a base six number has a place value that is a power of six. The lowest four powers of 6, beginning with 1, are 
Example Question #1 : Numbers And Operations
How many elements of the set 
Three
None
One
Two
None
The square root of an integer is irrational if it is not an integer itself. As can be calculated, all three of these square roots are not integers, so none are rational.
Example Question #2 : Ged Math
How many elements of the set 
One
Two
Three
None
Two
0 and 1 are both integers and are therefore rational numbers. 
Example Question #2 : Ged Math
To how many of the following sets does the number 
I) The set of whole numbers
II) The set of integers
III) The set of rational numbers
One
Two
Three
None
Two
The whole numbers comprise 0 and the positive integers. 
Example Question #3 : Ged Math
Which of the following cannot be equal to 
We look for ways to write 20 as the product of three integers, then we find the sum of the integers in each situation. They are:
Sum:
Sum:
Sum:
Sum:
9, 10, and 13 are among the possible sums, but 15 is not, so that is the correct response.
Example Question #5 : Ged Math
To how many of the following sets does the number
I) The set of whole numbers
II) The set of integers
III) The set of rational numbers
Three
None
Two
One
Two
The whole numbers comprise 0 and the positive integers.
Example Question #1 : Ged Math
Which of the following could be equal to 
20 can be factored as:
I)
II)
III)
The positive difference of the factors can be any of:
Of the four choices, only 8 is possible.
Example Question #2 : Ged Math
How many subsets does the set 
The number of subsets of a set with 
Example Question #7 : Ged Math
How many elements are in a set that has exactly 64 subsets?
A set with 
Example Question #5 : Ged Math
Which of the following could be equal to 
We need to find ways to factor 32 such that the three factors are different, and then find the sum of those factors in each case.
32 can be factored as the product of three integers in five differrent ways:
I) 
II) 
III)
IV)
V)
Of the five ways, only the second and third involve three distinct factors.
In Case II, the sum of the factors is
In Case III, the sum of the factors is
The only possible correct response is 19.
