Python Coding Challenge - Question with Answer (ID 171026)

 

Explanation:

Step 1: Understand the ** operator

The ** operator is used for exponentiation, which means raising a number to a power.

2**-1

Here:

- 2 is the base.

- -1 is the exponent.

Step 2: Understand the negative exponent

A negative exponent means taking the reciprocal of the base raised to the corresponding positive power.

\[

a^{-n}=\{1}{a^n}

\]

Therefore:

\[

2^{-1}=\{1}{2^1}

\]

Step 3: Calculate the value

Since \(2^1=2\):

\[

\frac{1}{2}=0.5

\]

Step 4: Final output

0.5
