Calculate (1/3)³: Evaluating the Cube of a Simple Fraction

Question

Insert the corresponding expression:

(13)3= \left(\frac{1}{3}\right)^3=

Video Solution

Step-by-Step Solution

To solve the expression (13)3 \left(\frac{1}{3}\right)^3 , we need to apply the rule for exponents of a fraction, which states:

(ab)n=anbn \left(\frac{a}{b}\right)^n = \frac{a^n}{b^n}

Using this property, we can rewrite the fraction with its exponent as follows:

(13)3=1333 \left(\frac{1}{3}\right)^3 = \frac{1^3}{3^3}

Now, calculate the powers of the numerator and the denominator separately:

  • 13=1 1^3 = 1

  • 33=27 3^3 = 27

Thus, putting it all together, we have:

1333=127 \frac{1^3}{3^3} = \frac{1}{27}

This shows that raising both the numerator and the denominator of a fraction to a power involves calculating the power of each part separately and then constructing a new fraction.

The solution to the question is: 127 \frac{1}{27}

Answer

127 \frac{1}{27}
