Calculating fractions raised to a power might seem tricky at first, but it can be straightforward once you understand the process. In this guide, we’ll explore how to calculate ( \frac{1}{3} ) raised to the power of 4. We will break down the steps and provide some useful tips to make this concept crystal clear. Let’s dive in! ✨
Understanding Exponents
Exponents are a way to denote repeated multiplication. When we say ( a^n ), we mean multiplying ( a ) by itself ( n ) times. For instance, ( 2^3 ) means ( 2 \times 2 \times 2 ).
Key Concept: Fractional Exponents
When working with fractions, the exponent applies to both the numerator and the denominator. For example:
[ \left(\frac{a}{b}\right)^n = \frac{a^n}{b^n} ]
This means that you will raise the numerator and the denominator to the power of ( n ).
Step-by-Step Calculation of ( \frac{1}{3}^4 )
Now let's apply this understanding to calculate ( \frac{1}{3} ) to the power of 4.
-
Write the Fraction: [ \frac{1}{3} ]
-
Apply the Exponent: We will raise both the numerator and the denominator to the 4th power. [ \left(\frac{1}{3}\right)^4 = \frac{1^4}{3^4} ]
-
Calculate Each Part:
- Calculate ( 1^4 ): [ 1^4 = 1 ]
- Calculate ( 3^4 ): [ 3^4 = 3 \times 3 \times 3 \times 3 ]
Let's break down ( 3^4 ):
- First, calculate ( 3 \times 3 = 9 )
- Next, calculate ( 9 \times 3 = 27 )
- Finally, calculate ( 27 \times 3 = 81 )
So, ( 3^4 = 81 ).
-
Combine Results: Now, we can combine the results from the numerator and the denominator: [ \left(\frac{1}{3}\right)^4 = \frac{1^4}{3^4} = \frac{1}{81} ]
Therefore, ( \frac{1}{3} ) to the power of 4 is ( \frac{1}{81} ). 🎉
Important Note:
“When raising a fraction to a power, always apply the exponent to both the numerator and the denominator to get accurate results.”
