Answer 2

Let's break down each expression step by step:

1. 2! + 3! + 4! + 1/2 - 1/3

First, let's calculate the factorials:

2! = 2 * 1 = 2 3! = 3 * 2 * 1 = 6 4! = 4 * 3 * 2 * 1 = 24

Now, let's add everything up:

2 + 6 + 24 + 1/2 - 1/3

To add fractions, we need to find a common denominator. The common denominator for 2, 6, and 24 is 24 (the least common multiple of 2, 3, and 4). So, we rewrite 1/2 and 1/3 with a denominator of 24:

2 + 6 + 24 + 12/24 - 8/24

Now, we can add the fractions:

2 + 6 + 24 + (12 - 8)/24

Now, simplify the fraction:

2 + 6 + 24 + 4/24

Combine like terms:

32 + 4/24

Now, convert the fraction to a mixed number:

32 + 1/6

The result is 32 1/6.

2. -33! - 1/3 + 1/9 - 3

As for the expression with -33!, we need to calculate the factorial of -33:

(-33)! is not defined since factorials are only defined for non-negative integers.

So, the expression cannot be computed.

3. 4! + 1/4 + 1/16 - 1/64

Let's calculate the factorial and work with the fractions:

4! = 4 * 3 * 2 * 1 = 24

Now, rewrite the fractions with a common denominator of 64:

24 + 16/64 + 4/64 - 1/64

Combine the fractions:

24 + (16 + 4 - 1)/64

24 + 19/64

The result is 24 19/64.

So, the answers to the given expressions are as follows:

1. 2! + 3! + 4! + 1/2 - 1/3 = 32 1/6
2. -33! - 1/3 + 1/9 - 3 = undefined (Factorial of a negative number is not defined)
3. 4! + 1/4 + 1/16 - 1/64 = 24 19/64
