Example Question #81 : Integer Operations
Evaluate:
Example Question #82 : Integer Operations
Solve
First, distribute the exponents to the numerators and denominators:
.
Then, rewrite the problem in expanded form:
Next, rewrite the problem so that you only have prime factors in both numerators and denominators:
.
Last, simplify by "canceling out" like terms, leaving you with
and multiply across both numerators and denominators, which will give you .
Example Question #83 : Integer Operations
Example Question #84 : Integer Operations
Multiply and express the product in scientific notation:
Use your power properties to multiply these numbers.
This is not in scientific notation, so adjust as follows:
Example Question #85 : Real Numbers
Multiply and express the product in scientific notation:
Use your power properties to multiply these numbers.
This is not in scientific notation, so adjust as follows:
Example Question #83 : Integer Operations
Rewrite as a number in base ten:
Example Question #87 : Real Numbers
Rewrite as a number in base ten:
Example Question #88 : Real Numbers
Simplify the following:
In this problem, you need to use the proper order of operations to find the correct answer: PEMDAS (Parentheses, Exponents, Multiplication-Division, Addition-Subtraction).
Exponents show up first in this problem, so the first step is to simplify:
This results in:
The next step is the multiplication:
This results in:
The next step is to do the remaining addition and subtraction from left to right.
499 is your final answer.
Example Question #1 : Mathematical Relationships
Evaluate the expression.
Follow the correct order of operations: parenthenses, exponents, multiplication, division, addition, subtraction.
First, evaluate any terms in parenthesis.
Next, evaluate the exponent.
Divide.
Finally, add.
Example Question #11 : Proportionalities
The quantity x varies directly with y. If x is 26 when y is 100, find x when y is 200.
104
26
52
13
6.5
52
We must set up a proportion. Since x varies directly with y, when y is multiplied by 2, x is also multiplied by 2. 26 times 2 is 52.
Direct variation:
