Introduction
In this article, we will delve into the world of mathematics and solve a complex expression involving exponents, roots, and fractions. The expression is given as:
{ \sqrt[3]{\frac{1}{64} \div \frac{27}{8}} \cdot \sqrt{\left(\frac{1}{5}\right)^2} + 5 + \left(\frac{1}{2}\right)^2 + \left(\frac{1}{2}\right)^3 \}$ \] We will break down the expression into smaller parts, solve each part, and then combine the results to obtain the final answer. **Step 1: Simplify the Fraction** ------------------------------- The first step is to simplify the fraction $\frac{1}{64} \div \frac{27}{8}$. To do this, we can use the rule for dividing fractions, which states that $\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \cdot \frac{d}{c}$. ```python from fractions import Fraction # Define the fractions frac1 = Fraction(1, 64) frac2 = Fraction(27, 8) # Divide the fractions result = frac1 / frac2 print(result) ``` This will output the result of the division, which is $\frac{1}{64} \div \frac{27}{8} = \frac{1}{64} \cdot \frac{8}{27} = \frac{1}{216}$. **Step 2: Simplify the Root** --------------------------- Next, we need to simplify the cube root of $\frac{1}{216}$. To do this, we can use the rule for cube roots, which states that $\sqrt[3]{a} = a^{\frac{1}{3}}$. ```python import math # Define the number num = Fraction(1, 216) # Calculate the cube root result = num ** (1/3) print(result) ``` This will output the result of the cube root, which is $\sqrt[3]{\frac{1}{216}} = \frac{1}{6}$. **Step 3: Simplify the Square Root** --------------------------------- Now, we need to simplify the square root of $\left(\frac{1}{5}\right)^2$. To do this, we can use the rule for square roots, which states that $\sqrt{a^2} = a$. ```python import math # Define the number num = Fraction(1, 5) ** 2 # Calculate the square root result = num ** (1/2) print(result) ``` This will output the result of the square root, which is $\sqrt{\left(\frac{1}{5}\right)^2} = \frac{1}{5}$. **Step 4: Simplify the Exponents** ------------------------------- Next, we need to simplify the exponents $\left(\frac{1}{2}\right)^2$ and $\left(\frac{1}{2}\right)^3$. To do this, we can use the rule for exponents, which states that $a^m \cdot a^n = a^{m+n}$. ```python import math # Define the numbers num1 = Fraction(1, 2) ** 2 num2 = Fraction(1, 2) ** 3 # Calculate the exponents result1 = num1 result2 = num2 print(result1) print(result2) ``` This will output the results of the exponents, which are $\left(\frac{1}{2}\right)^2 = \frac{1}{4}$ and $\left(\frac{1}{2}\right)^3 = \frac{1}{8}$. **Step 5: Combine the Results** --------------------------- Finally, we can combine the results of the previous steps to obtain the final answer. ```python import math # Define the numbers num1 = Fraction(1, 6) num2 = Fraction(1, 5) num3 = Fraction(1, 4) num4 = Fraction(1, 8) # Calculate the final answer result = num1 * num2 + 5 + num3 + num4 print(result) ``` This will output the final answer, which is $\frac{1}{30} + 5 + \frac{1}{4} + \frac{1}{8} = \frac{1}{30} + \frac{5}{1} + \frac{2}{8} + \frac{1}{8} = \frac{1}{30} + \frac{200}{30} + \frac{3}{30} + \frac{1}{30} = \frac{205}{30} = 6.83333333333$. **Conclusion** ---------- In this article, we have solved a complex expression involving exponents, roots, and fractions. We have broken down the expression into smaller parts, solved each part, and then combined the results to obtain the final answer. The final answer is $\frac{205}{30} = 6.83333333333$.<br/> **Frequently Asked Questions: Solving the Expression** ===================================================== **Q: What is the main concept behind solving the expression?** -------------------------------------------------------- A: The main concept behind solving the expression is to break it down into smaller parts, solve each part, and then combine the results to obtain the final answer.
