Understanding Factorial and Fraction Multiplication in Mathematics: A Comprehensive Guide

Multiplication of factorials and fractions can often be a challenging task, yet it is an essential skill in advanced mathematics. This guide aims to break down the process and provide clarity to those navigating through these complex calculations.

Introduction to Factorials and Fractions

Factorials and fractions form an important part of mathematics and are used extensively in various fields such as combinatorics, probability, and analysis. A factorial of a number ( n ) (denoted by ( n! )) is the product of all positive integers up to ( n ), while fractions are used to represent ratios or parts of a whole.

Multiplying Factorials and Fractions

Consider the expression 2 × 7 × 6 × 8 × 5 × 9 × 4 × 9 × 3 × 5 × 4 × 1 × 5 × 713/4. Let's break it down step-by-step to understand the calculation.

Breaking Down the Expressions

First, let's simplify the expression by grouping the numbers that are easy to multiply:

2 × 7 14 14 × 6 84 84 × 8 672 672 × 5 3360 3360 × 9 30240 30240 × 4 120960 120960 × 9 1088640 1088640 × 3 3265920 3265920 × 5 16329600 16329600 × 4 65318400 65318400 × 1 65318400 65318400 × 5 326592000 326592000 × 713/4 22861440003.25

Distinct Computation Steps

Let's further break down the computation:

Calculate the factorial part: 9! 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 362880 Multiply by a combination of other terms: 45^27913/4 simplified into smaller steps Isolate the factorial and the four terms:

y  362880 * (45^27913/4)
Further simplify: 45^27913/4 630013/4 Combine all values: 362880 * 630013/4 22861440003.25 Final output:

y  22861440003 1/4
