Simplify. $$ \left(x^{3} \cdot x^{2}\right)^{2} $$

Short Answer

Expert verified
The simplified form is \(x^{10}\).

Step by step solution

01

Apply Product of Powers Rule

First, simplify the expression within the parentheses using the product of powers rule. This rule states that when you multiply two exponents with the same base, you add the exponents: \(x^a \cdot x^b = x^{a+b}\).Thus, \(x^3 \cdot x^2 = x^{3+2} = x^5\).The expression becomes:\[(x^5)^2.\]
02

Apply Power of a Power Rule

Now, simplify \((x^5)^2\) using the power of a power rule, which states that when raising a power to another power, you multiply the exponents:\((x^m)^n = x^{m \cdot n}\).So, \((x^5)^2 = x^{5 \cdot 2} = x^{10}.\)The simplified expression is:\[x^{10}.\]

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Product of Powers Rule
The Product of Powers Rule is a fundamental concept when dealing with exponents in algebra. It provides a straightforward way to simplify expressions where you multiply terms with the same base. When two exponents share this common base, you simply add the exponents. For example, if you have \( x^a \) multiplied by \( x^b \), the result is \( x^{a+b} \). This is because the base remains the same, and you are essentially counting how many times the base is used as a factor in total.
  • Example: \( x^3 \cdot x^2 \) can be rewritten as \( x^{3+2} = x^5 \).
The simplicity of this rule makes it very useful, especially when you encounter long strings of the same base. It not only streamlines computations but also helps to recognize patterns in algebraic expressions for further simplification.
Power of a Power Rule
The Power of a Power Rule involves expressions where an exponent is raised to another exponent. This rule is useful when simplifying expressions like \((x^m)^n\). Applying this rule involves multiplying the two exponents instead of adding them. Thus, it converts the expression into \(x^{m \cdot n}\).
  • Example: \((x^5)^2\) simplifies to \(x^{5 \times 2} = x^{10}\).
This formula comes in handy when dealing with nested exponentiations, ensuring that all operations are efficiently simplified. Understanding this helps to grasp how nested powers condense into a single exponentiated term.
Simplification of Expressions
Simplifying expressions is the process of reducing an expression into the simplest form possible, making it easier to understand or to use in further calculations. This often involves applying rules such as the Product of Powers and Power of a Power rules. By using these techniques, you can transform complex expressions into more manageable forms.
  • Start by looking for common bases and apply the Product of Powers Rule when multiplying terms.
  • Use the Power of a Power Rule when exponents are raised to another power to minimize the expression.
In our original problem, starting from \((x^3 \cdot x^2)^2\), we simplified it to \(x^{10}\) by using these rules in sequence. Always aim to rewrite algebraic expressions in their simplest form to enhance clarity and mathematical insight.

SOCIAL SCIENCE: Equal Pay for Equal Work Women's pay has often lagged behind men's, although Title VII of the Civil Rights Act requires equal pay for equal work. Based on data from \(2000-2008\), women's annual earnings as a percent of men's can be approximated by the formula \(y=0.51 x+77.2, \quad\) where \(x\) is the number of years since 2000 . (For example, \(x=10\) gives \(y=82.3\), so in 2010 women's wages were about \(82.3 \%\) of men's wages.) a. Graph this line on the window \([0,30]\) by \([0,100]\). b. Use this line to predict the percentage in the year 2020\. [Hint: Which \(x\) -value corresponds to 2020 ? Then use TRACE, EVALUATE, or TABLE.] c. Predict the percentage in the year 2025 .

Can the graph of a function have more than one \(x\) intercept? Can it have more than one \(y\) -intercept?

$$ \text { How do the graphs of } f(x) \text { and } f(x+10)+10 \text { differ? } $$

ATHLETICS: Cardiovascular Zone Your maximum heart rate (in beats per minute) may be estimated as 220 minus your age. For maximum cardiovascular effect, many trainers recommend raising your heart rate to between \(50 \%\) and \(70 \%\) of this maximum rate (called the cardio zone). a. Write a linear function to represent this upper limit as a function of \(x\), your age. Then write a similar linear function to represent the lower limit. Use decimals instead of percents. b. Use your functions to find the upper and lower cardio limits for a 20 -year-old person. Find the cardio limits for a 60 -year-old person.

ECONOMICS: Per Capita Personal Income In the short run, per capita personal income (PCPI) in the United States grows approximately linearly. In 2001 PCPI was \(30.4\), and in 2009 it had grown to \(39.2\) (both in thousands of dollars). a. Use the two given (year, PCPI) data points \((1,30.4)\) and \((9,39.2)\) to find the linear relationship \(y=m x+b\) between \(x=\) years since 2000 and \(y=\mathrm{PCPI}\). b. Use your linear relationship to predict PCPI in 2020 .
