Evaluate the expression.

[tex]\[
\left(\frac{1}{5}\right)^4
\][/tex]

[tex]\[
\left(\frac{1}{5}\right)^4 =
\][/tex]



Answer :

To evaluate the expression [tex]\(\left(\frac{1}{5}\right)^4\)[/tex], we follow these steps:

1. Identify the base and the exponent in the expression. Here, the base is [tex]\(\frac{1}{5}\)[/tex] and the exponent is 4.
2. Understand that raising a fraction to an exponent means multiplying the fraction by itself as many times as indicated by the exponent. In this case, we will multiply [tex]\(\frac{1}{5}\)[/tex] by itself 4 times.

[tex]\[ \left(\frac{1}{5}\right)^4 = \frac{1}{5} \times \frac{1}{5} \times \frac{1}{5} \times \frac{1}{5} \][/tex]

3. Calculate the multiplication of the fractions manually or recognize that each multiplication of [tex]\(\frac{1}{5}\)[/tex] results in the base raised to the current power step.

4. Understanding that [tex]\(\left(a^m \times a^n = a^{m+n}\right)\)[/tex], we can simplify the computations.

5. So, the calculation proceeds as follows:

[tex]\[ \frac{1}{5} \times \frac{1}{5} = \frac{1}{25} \][/tex]

Next,

[tex]\[ \frac{1}{25} \times \frac{1}{5} = \frac{1}{125} \][/tex]

Finally,

[tex]\[ \frac{1}{125} \times \frac{1}{5} = \frac{1}{625} \][/tex]

6. Thus,

[tex]\[ \left(\frac{1}{5}\right)^4 = \frac{1}{625} \][/tex]

7. Converting [tex]\(\frac{1}{625}\)[/tex] to its decimal form, we find the answer to be approximately [tex]\(0.0016000000000000003\)[/tex].

So, the final result is:

[tex]\[ \left(\frac{1}{5}\right)^4 = 0.0016000000000000003 \][/tex]
