Example Question #111 : Numbers And Operations
Solve:
It is not necessary to evaluate both terms and multiply.
According to the rules of exponents, when we have the same bases raised to some power that are multiplied with each other, we can add the powers.
This term can be rewritten as a fraction.
The answer is:
Example Question #551 : Isee Upper Level (Grades 9 12) Mathematics Achievement
Which of the following is equivalent to the expression below?
When exponents are multiplied by one another, and the base is the same, the exponents can be added together.
The first step is to try to create a common base.
Given that the square of 2 is for, the expression can be rewritten as:
Example Question #111 : Numbers And Operations
Simplify:
Based on the product rule for exponents in order to multiply two exponential terms with the same base, add their exponents:
So we can write:
Example Question #551 : Isee Upper Level (Grades 9 12) Mathematics Achievement
Refer to the above Venn diagram.
Define universal set , the set of natural numbers.
Define sets and as follows:
Which of the following numbers is an element of the set represented by the gray area in the diagram?
The gray area represents the set of all elements that are in but not in .
is the set of integers that, when divided by 3, yield remainder 2. Therefore, we can eliminate 102 and 105, both multiples of 3, and 103, which, when divided by 3, yields remainder 1.
is the set of integers that, when divided by 4, yield remainder 1. Since we do not want an element from this set, we can eliminate 101, but not 104.
104 is the correct choice.
Example Question #552 : Isee Upper Level (Grades 9 12) Mathematics Achievement
In the above Venn diagram, the universal set is defined as . Each of the eight letters is placed in its correct region.
What is ?
is the intersection of sets and - that is, the set of all elements of that are elements of both and . We want all of the letters that fall in both circles, which from the diagram can be seen to be and . Therefore,
Example Question #553 : Isee Upper Level (Grades 9 12) Mathematics Achievement
In the above Venn diagram, the universal set is defined as . Each of the eight letters is placed in its correct region. Which of the following is equal to ?
is the complement of - the set of all elements in not in .
is the intersection of sets and - that is, the set of all elements of that are elements of both and . Therefore, is the set of all elements that are not in both and , which can be seen from the diagram to be all elements except and . Therefore,
.
Example Question #4 : Data Analysis And Probability
In the above Venn diagram, the universal set is defined as . Each of the eight letters is placed in its correct region. Which of the following is equal to ?
is the complement of - the set of all elements in not in .
is the union of sets and - the set of all elements in either or . Therefore, is the set of all elements in neither nor , which can be seen from the diagram to be only one element - . Therefore,
Example Question #554 : Isee Upper Level (Grades 9 12) Mathematics Achievement
The following Venn diagram depicts the number of students who play hockey, football, and baseball. How many students play football and baseball?
The number of students who play football or baseball can by finding the summer of the number of students who play football alone, baseball alone, baseball and football, and all three sports.
Example Question #1 : Data Analysis And Probability
A class of students was asked whether they have cats, dogs, or both.The results are depicted in the following Venn diagram. How many students do not have a dog?
First, calculate the number of students with a dog:
Next, subtract the number of students with a dog from the total number of students.
Example Question #1 : How To Find The Answer From A Table
If a standard die is rolled, what is the probability of getting a 1 or a 2?
We need to know the total number of possibilities, and the total number of ways to achieve our goal.
A standard die has 6 faces, so there are a total of 6 numbers that we could roll.
We want to roll a 1 or a 2, which means there are 2 ways that we can succeed (rolling a 1 or a 2).
Thus, we have a probability of success as which reduces to .
