Mathematical expressions can be complex and daunting, making it challenging to simplify them. However, with a clear understanding of the rules of arithmetic and algebra, we can break down even the most intricate expressions into manageable parts. In this article, we will focus on simplifying the given expression: $\frac{15(5492)(838)^2}{15(15-1)}$. We will use a step-by-step approach to evaluate this expression and provide a clear understanding of the mathematical concepts involved.

Understanding the Expression

The given expression is a fraction, which consists of two parts: the numerator and the denominator. The numerator is $15(5492)(838)^2$, and the denominator is $15(15-1)$. To simplify this expression, we need to follow the order of operations (PEMDAS):

1. Parentheses: Evaluate the expressions inside the parentheses.
2. Exponents: Evaluate any exponential expressions.
3. Multiplication and Division: Evaluate any multiplication and division operations from left to right.
4. Addition and Subtraction: Evaluate any addition and subtraction operations from left to right.

Simplifying the Numerator

The numerator is $15(5492)(838)^2$. To simplify this expression, we need to follow the order of operations:

1. Evaluate the expression inside the parentheses: $5492$ is already simplified.
2. Evaluate the exponential expression: $(838)^2 = 838 \times 838 = 702,884$.
3. Multiply the results: $15 \times 5492 \times 702,884 = 4,444,111,120$.

Simplifying the Denominator

The denominator is $15(15-1)$. To simplify this expression, we need to follow the order of operations:

1. Evaluate the expression inside the parentheses: $15-1 = 14$.
2. Multiply the results: $15 \times 14 = 210$.

Simplifying the Expression

Now that we have simplified the numerator and the denominator, we can simplify the expression:

$\frac{15(5492)(838)^2}{15(15-1)} = \frac{4,444,111,120}{210}$

To simplify this expression, we can divide the numerator by the denominator:

$\frac{4,444,111,120}{210} = 21,111,120$

Conclusion

In this article, we simplified the given expression: $\frac{15(5492)(838)^2}{15(15-1)}$. We followed the order of operations (PEMDAS) to evaluate the expression and provided a clear understanding of the mathematical concepts involved. By breaking down the expression into manageable parts and following the rules of arithmetic and algebra, we were able to simplify the expression and arrive at the final result.

Q&A Guide

Q: What is the order of operations (PEMDAS)?

A: The order of operations (PEMDAS) is a set of rules that dictate the order in which mathematical operations should be performed. The acronym PEMDAS stands for: + Parentheses: Evaluate expressions inside parentheses first. + Exponents: Evaluate any exponential expressions next. + Multiplication and Division: Evaluate any multiplication and division operations from left to right. + Addition and Subtraction: Evaluate any addition and subtraction operations from left to right.

Q: How do I simplify a complex mathematical expression?

A: To simplify a complex mathematical expression, follow the order of operations (PEMDAS) and break down the expression into manageable parts. Evaluate any expressions inside parentheses, then evaluate any exponential expressions, followed by any multiplication and division operations, and finally any addition and subtraction operations.

Q: What is the difference between multiplication and division?

A: Multiplication and division are both operations that involve numbers, but they have different rules. Multiplication involves multiplying two or more numbers together, while division involves dividing one number by another. For example, $3 \times 4 = 12$ and $12 \div 3 = 4$.

Q: How do I evaluate expressions with exponents?

A: Exponents are a shorthand way of writing repeated multiplication. For example, $2^3 = 2 \times 2 \times 2 = 8$. To evaluate an expression with an exponent, simply multiply the base number by itself as many times as the exponent indicates.

Q: What is the difference between addition and subtraction?

A: Addition and subtraction are both operations that involve numbers, but they have different rules. Addition involves combining two or more numbers together, while subtraction involves finding the difference between two numbers. For example, $3 + 4 = 7$ and $7 - 3 = 4$.

Q: How do I simplify expressions with fractions?

A: Fractions are a way of expressing part of a whole. To simplify a fraction, find the greatest common divisor (GCD) of the numerator and denominator and divide both numbers by the GCD. For example, $\frac{6}{8} = \frac{3}{4}$.

Q: What is the difference between a variable and a constant?

A: A variable is a letter or symbol that represents a value that can change, while a constant is a value that does not change. For example, $x$ is a variable, while $5$ is a constant.

Q: How do I solve equations with variables?

A: To solve an equation with a variable, isolate the variable on one side of the equation. This can be done by adding, subtracting, multiplying, or dividing both sides of the equation by the same value. For example, $x + 3 = 5$ can be solved by subtracting $3$ from both sides of the equation, resulting in $x = 2$.
