Final answer:
The correct lambda expression is lambda num: num * num. The correct lambda expression for squaring an integer is 'lambda num: num * num', which multiplies the number by itself. The correct answer is A.
Step-by-step explanation:
The correct lambda expression that converts an integer into the square of that integer is lambda num: num * num.
For example, if we use the lambda expression on the integer 5, it would be: (lambda num: num * num)(5) = 5 * 5 = 25.
This lambda expression takes the input integer and returns the square of that integer as the output.
The correct lambda expression for squaring an integer is 'lambda num: num * num', which multiplies the number by itself.
The lambda expression that converts an integer into the square of that integer is lambda num: num * num. This expression defines an anonymous function that takes a single argument, num, and returns the result of multiplying num by itself, effectively squaring the number. In the context of integer powers, squaring a number, such as 5, is analogous to raising it to the power of 2: 52 = 5 x 5 = 25.
The correct lambda expression that converts an integer into the square of that integer is option (d): `lambda num: num * num`. Lambda expressions in Python are used to create anonymous functions, and in this case, the lambda expression takes a single argument `num` and returns the result of multiplying `num` by itself, effectively calculating the square of the integer. The syntax is concise, with `lambda` denoting the start of the anonymous function, followed by the input parameter `num`, a colon to separate the parameter from the expression, and `num * num` as the computation to be performed.
Options (a), (b), and (c) are incorrect. Option (a) seems to have a syntax error with the use of quotation marks, and it lacks the multiplication operation. Option (b) contains an incorrect multiplication symbol (∗2), and option (c) also has a syntax error with the use of quotation marks and lacks the multiplication operation.
In summary, for squaring an integer using a lambda expression, the correct syntax is `lambda num: num * num`, as demonstrated in option (d).
